15.3 A 477mW NoC-Based Digital Baseband for MIMO 4G SDR

by Fabien Clermidy, Christian Bernard, Romain Lemaire, Jerome Martin, Ivan Miro-panades, Yvain Thonnart, Pascal Vivet, Norbert Wehn
"... Baseband processing for advanced Telecom applications have to face two con-tradictory issues [1]. The first one is the flexibility required, with the exploding number of modes for a single protocol (e.g. 63 for 3GPP-LTE), the number of protocols to be supported by a single chip (>10 in 2010) and ..."

1Spatial Compressive Sensing for MIMO Radar

by Marco Rossi, Student Member, Er M. Haimovich, Yonina C. Eldar
"... Abstract—We study compressive sensing in the spatial domain to achieve target localization, specifically direction of arrival (DOA), using multiple-input multiple-output (MIMO) radar. A sparse localization framework is proposed for a MIMO array in which transmit and receive elements are placed at ra ..."

is guaranteed if the product of the number of transmit and receive elements, MN (which is also the number of degrees of freedom), scales with K (logG)2, where K is the number of targets and G is proportional to the array aperture and determines the angle resolution. In contrast with a filled virtual MIMO array

ENERGY-EFFICIENT SOFTWARE-DEFINED RADIO SOLUTIONS FOR MIMO-BASED BROADBAND COMMUNICATION

by Bruno Bougard, Andre Bourdoux, Frederik Naessens, Miguel Glassee, Veerle Derudder, Liesbet Van Der Perre
"... Multi-antenna transmission over multi-input, multi-output (MIMO) channels are considered in almost all recent broadband wireless communication standards. Besides, the fast-pacing diver-sity and evolution of those standards, next to the deep submicron integration cost explosion, urges multi-mode reco ..."

-mode reconfigurable solu-tions. Software Defined Radio (SDR) is envisioned to enable low-cost, high-volume multi-mode baseband modems both for base-station and user terminals. Yet, supporting high-throughput MIMO standard with limited energy budget as in user terminals is a challenge for SDR architectures. With Space

Subspace Communication

by Josep Font-segura, Prof Gregori , 2014
"... We are surrounded by electronic devices that take advantage of wireless technologies, from our computer mice, which require little amounts of information, to our cellphones, which demand increasingly higher data rates. Until today, the coexistence of such a variety of services has been guaranteed by ..."

1Sub-Nyquist Sampling: Bridging Theory and Practice

by Moshe Mishali, Yonina C. Eldar
"... [ A review of past and recent strategies for sub-Nyquist sampling] Signal processing methods have changed substantially over the last several decades. In modern applications, an increasing number of functions is being pushed forward to sophisticated software algorithms, leaving only delicate finely- ..."

-tuned tasks for the circuit level. Sampling theory, the gate to the digital world, is the key enabling this revolution, encompassing all aspects related to the conversion of continuous-time signals to discrete streams of numbers. The famous Shannon-Nyquist theorem has become a landmark: a mathematical

RICE UNIVERSITY Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing

by Jason Noah Laska , 2011
"... The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demon-strated that structured signals can be acquired with just a small number of linear measurements, on the order of t ..."

1On the Subtleties of q-PAM Linear Physical-Layer Network Coding

by Long Shi, Soung Chang Liew, Lu Lu
"... Abstract—This paper investigates various subtleties of ap-plying linear physical-layer network coding (PNC) with q-level pulse amplitude modulation (q-PAM) in two-way relay channels (TWRC). A critical issue is how the PNC system performs when the received powers from the two users at the relay are i ..."
