Peter Jan Lüthi from Switzerland has to his credit this Ph.D. Thesis - VLSI Circuits for MIMO Preprocessing.This is related to design, implementation and demonstration of suitable algorithms for MIMO wireless communication.
Real-time 4x4 MIMO-OFDM Testbed
"The latest mobile applications and the growing number of wireless users are increasing the demand for high-throughput wireless access solutions. Multiple-input multiple-output (MIMO) technology combined with orthogonal frequency-division multiplexing (OFDM) constitute today's most promising approach to exploit the limited radio frequency resources in a highly efficient way.
