摘要：
In this paper, a new joint channel estimation and detection algorithm for frequency selective,fading Multiple-Input Multiple-Output (MIMO) channels is proposed. In the channel estimation section, using a generalized form of Least Square (LS) algorithm, a very accurate estimate of channel parameters is obtained. The procedure of detection is done in two stages. In the first stage the Inter-Symbol-Interference (ISI) of previous stages is subtracted and then in the second stage, using a joint detection algorithm, the transmitted symbols are estimated. Parallel-Interference-Cancellator (PIC) and Minimum-Mean-Square-Estimator (MMSE) are used as MIMO detectors. The efficiency of the proposed algorithm, in time-varying MIMO channels is confirmed through various simulations.
