Semi-blind signal detection for mimo and mimo-ofdm systems
... Rake-based multi- user detection technique is proposed for quasi-synchronous MIMO systems. The first step separates the multi- user multi- path signal vector into multi- user single-path signal vectors ... MIMO-OFDM system 1.3 Semi-blind signal detection Traditional signal detection techniques use training sequences to estimate the channel as the first step. Signal detection then follows equalization. ... signals are combined using the Rake receiver principle for multi- user detection. It is shown that the output of the combiner yields the estimated transmitted signals. It follows that the multi- user...
