Low End Theory probes the much-mythologized field of bass and low-frequency sound. It begins in music but quickly moves far beyond, following vibratory phenomena across time, disciplines and disparate cultural spheres (including hauntings, laboratories, organ workshops, burial mounds, sound art, studios, dancefloors, infrasonic anomalies, and a global mystery called The Hum). Low End Theory asks what it is about bass that has fascinated us for so long and made it such a busy site of bio-technological experimentation, driving developments in science, technology, the arts, and religious culture. The guiding question is not so much what we make of bass, but what it makes of us: how does it undulate and unsettle; how does it incite; how does it draw bodily thought into new equations with itself and its surroundings? Low End Theory is the first book to survey this sonorous terrain and devise a conceptual language proper to it. With its focus on sound's structuring agency and the multi-sensory aspects of sonic experience, it stands to make a transformative contribution to the study of music and sound, while pushing scholarship on affect, materiality, and the senses into fertile new territory. Through energetic and creative prose, Low End Theory works to put thought in touch with the vibratory encounter as no scholarly book has done before.

Low End is an exciting vintage-style crime noire novel dealing with modern issues in the style of the classic 1940's mystery writers. Low End is murder mystery with a twist involving a least-likely detective, a disillusioned, New York City musician named Gary Morrissey. Gary finds himself involved in a murder investigation of his own making when shadows of government corruption and hints of premeditated genocide are cast over a friend's murder. The author's own experiences are reflected in his lead character, whose love for New York City and for its less-than-attractive suburbs and citizens emanates from every page and whose musical knowledge and expertise provide a unique background for the events that unfold. Some mild language and violence, no sex.

Massive MIMO (multiple-input–multiple-output) is a multi-antenna technology for cellular wireless communication, where the base station uses a large number of individually controllable antennas to multiplex users spatially. This technology can provide a high spectral efficiency. One of its main challenges is the immense hardware complexity and cost of all the radio chains in the base station. To make massive MIMO commercially viable, inexpensive, low-complexity hardware with low linearity has to be used, which inherently leads to more signal distortion. This thesis investigates how the degenerated linearity of some of the main components—power amplifiers, analog-to-digital converters (ADCs) and low-noise amplifiers—affects the performance of the system, with respect to data rate, power consumption and out-of-band radiation. The main results are: Spatial processing can reduce PAR (peak-to-average ratio) of the transmit signals in the downlink to as low as 0B; this, however, does not necessarily reduce power consumption. In environments with isotropic fading, one-bit ADCs lead to a reduction in effective signal-to-interference-and-noise ratio (SINR) of 4dB in the uplink and four-bit ADCs give a performance close to that of an unquantized system. An analytical expression for the radiation pattern of the distortion from nonlinear power amplifiers is derived. It shows how the distortion is beamformed to some extent, that its gain never is greater than that of the desired signal, and that the gain of the distortion is reduced with a higher number of served users and a higher number of channel taps. Nonlinear low-noise amplifiers give rise to distortion that partly combines coherently and limits the possible SINR. It is concluded that spatial processing with a large number of antennas reduces the impact of hardware distortion in most cases. As long as proper attention is paid to the few sources of coherent distortion, the hardware complexity can be reduced in massive MIMO base stations to overcome the hardware challenge and make massive MIMO commercial reality. Massiv MIMO (eng: multiple-input–multiple-output) är en flerantennsteknologi för cellulär trådlös kommunikation, där basstationen använder ett stort antal individuellt styrbara antenner för att multiplexa användare i rummet. Denna teknologi kan tillhandahålla en hög spektral effektivitet. En av dess främsta utmaningar är den enorma hårdvarukomplexiteten och kostnaden hos basstationens alla radiokedjor. För att massiv MIMO skall bli kommersiellt attraktivt, måste billiga, enkla hårdvarukomponenter med låg linjäritet användas, vilket oundvikligen leder till mer signaldistorsion. Denna avhandling undersöker hur den försämrade linjäriteten hos några av huvudkomponenterna – effektförstärkare, analog-digital-omvandlare (AD-omvandlare) och lågbrusförstärkare – påverkar systemets prestanda, i termer av datatakt, effektförbrukning och utombandsstrålning. Huvudresultaten är: Rumslig signalbehandling kan reducera sändsignalernas toppvärde i nerlänken ända ner till 0dB, vilket dock inte nödvändigtvis minskar effektförbrukningen. I miljöer med isotrop fädning leder enbits-AD-omvandlare till 4dB lägre signal-till-interferens-och-brus-förhållande i upplänken, och fyrabits-AD-omvandlare ger en prestanda nära den ett system utan kvantisering kan uppnå. Ett analytiskt uttryck för strålningsmönstret för distorsionen från icke-linjära effektförstärkare härleds. Det visar hur distorsionen till viss del lobformas, att dess förstärkning aldrig är starkare än förstärkningen för den önskade signalen och att distorsionens förstärkning minskar med ett högre antal betjänade användare och ett högre antal kanaltappar. Icke-linjära lågbrusförstärkare ger upphov distorsion som delvis kombinerar koherent och begränsar det möjliga signal-till-brus-och-interferens-förhållandet. Slutsatsen är att rumslig signalbehandling med ett stort antal antenner reducerar hårdvarudistorsionens inverkan i de flesta fall. Så länge som de få källorna till koherent distorsion ges tillbörlig uppmärksamhet, kan hårdvarukomplexiteten minskas i basstationer för massiv MIMO för att övervinna hårdvaruutmaningen och göra massiv MIMO kommersiell verklighet. ????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????——???????????????——?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

Author Sasha Shakita Samson's journey wasn't paved with silver or gold or love and self-respect. Instead, it was filled with sex, drugs, violence, and murder. In Low End or No End, she shares her life story, one that presented a roller coaster of both ups and downs. In this memoir, she tells how she was born addicted to crack, her mother a drug addict. Although her mother tried to better herself and her family by moving from the west side of Chicago to the south side to give her kids a better life, drugs were her downfall. Samson and her brother, Julio, who was later murdered, were subjected to violence, poverty, homelessness, and hunger. Low End or No End narrates how these misfortunes impacted her life and how her faith and trust in God helped her withdraw from a life of drugs, promiscuous sex, and bad relationships. The experiences taught Samson who she was and her purpose in life and how to believe in love, her faith, her family, and her existence.

Massive MIMO (Multiple-Input Multiple-Output) base stations have proven, both in theory and in practice, to possess many of the qualities that future wireless communication systems will require. They can provide equally high data rates throughout their coverage area and can concurrently serve multiple low-end handsets without requiring wider spectrum, denser base station deployment or significantly more power than current base stations. The main challenge of massive MIMO is the immense hardware complexity and cost of the base station—each element in the large antenna array needs to be individually controllable and therefore requires its own radio chain. To make massive MIMO commercially viable, the base station has to be built from inexpensive simple hardware. In this thesis, it is investigated how the use of low-end power amplifiers and analog-to-digital converters (ADCs) affects the performance of massive MIMO. In the study of the signal distortion from low-end amplifiers, it is shown that in-band distortion is negligible in massive MIMO and that out-of-band radiation is the limiting factor that decides what power efficiency the amplifiers can be operated at. A precoder that produces transmit signals for the downlink with constant envelope in continuous time is presented to allow for highly power efficient low-end amplifiers. Further, it is found that the out-of-band radiation is isotropic when the channel is frequency selective and when multiple users are served; and that it can be beamformed when the channel is frequency flat and when few users are served. Since a massive MIMO base station radiates less power than today's base stations, isotropic out-of-band radiation means that low-end hardware with poorer linearity than required today can be used in massive MIMO. It is also shown that using one-bit ADCs—the simplest and least power-hungry ADCs—at the base station only degrades the signal-to-interference-and-noise ratio of the system by approximately 4 dB when proper power allocation among users is done, which indicates that massive MIMO is resistant against coarse quantization and that low-end ADCs can be used.
