Broadband Wireless Communications and Multiple-Input Multiple-Output
(MIMO) systems have been the focus of much research over the past decade. A
variety of MIMO detection algorithms have been proposed for detecting the data
signals from the multiple received and demodulated baseband signals. Among the
detectors, sphere decoding algorithms are known to be near-optimal but they are
relatively complicated and have variable detection latencies, and are therefore
inconvenient to implement. Also, the variable latency of most sphere decoder
algorithms makes them difficult to implement efficiently on parallel hardware.
This thesis work evaluates several alternative MIMO detectors and
proposes a near-optimal and efficiently parallelizable detector. The new MIMO
detector has much lower computational complexity than a sphere decoder, and has
a convenient parallel structure comprising multiple instances of the Vertical Bell
Laboratories Layered Space Time (V-BLAST) MIMO detection scheme. -
