Fast ML Detection for Quasi-Orthogonal STBCs of Rate 2 in Under-Determined Systems [Transactions Papers]

Abstract

A fast maximum-likelihood (ML) detection scheme is proposed for the important quasi-orthogonal space-time block codes (STBCs) of symbol rate 2 for three and four transmission antennas. In particular, the proposed scheme is applicable even to the under-determined system where the number of transmission antennas is larger than that of the receive antennas… (More)
