Low Complexity Receiver Structures for Space-Time Coded Multiple-Access Systems

EURASIP Journal on Advances in Signal Processing, 2002
Multiuser detection for space-time coded synchronous multiple-access systems in the presence of independent Rayleigh fading is considered. Under the assumption of quasi-static fading, it is shown that optimal (full diversity achieving) space-time codes ...
