Wireless @ Wired Speeds
This is a poster from the first 100x100 project meeting. It outlines some basic concepts in MIMO algorithm and system design at a relatively high, accessible level.
Channel Equalization Algorithms for MIMO Downlink and ASIP Architectures
Processors for mobile handsets in 3G cellular systems require: high speed, flexibility and low power dissipation. While computationally efficient, ASIC processors are often not flexible enough to support necessary ...
On Limits of Antenna Packing in Low Power Systems
We evaluate spectral efficiency limits of low power portable communication devices which are only constrained by fixed transceiver aperture G "subset&equal" real<sup>3</sup> for mounting antennas. A new notion of ...

Finite Rate Feedback Design for Multiple Transmit Antennas
Many practical systems employ a feedback channel to convey the channel state information to the transmitter.The capacity of the feedback channels is usually limited to a few bits per frame. We design feedback based ...
Implementation of a High Throughput Soft MIMO Detector on GPU
Multiple-input multiple-output (MIMO) significantly increases the throughput of a communication system by employing multiple antennas at the transmitter and the receiver. To extract maximum performance from a MIMO system, ...
A High Throughput Configurable SDR Detector for Multi-user MIMO Wireless Systems
Spatial division multiplexing (SDM) in MIMO technology significantly increases the spectral efficiency, and hence capacity, of a wireless communication system: it is a core component of the next generation wireless systems, ...
Cooperative Partial Detection Using MIMO Relays
Using multiple-input multiple-output (MIMO) relays in cooperative communication improves the data rate and reliability of the communication. The MIMO transmission, however, requires considerable resources for the detection ...
