A new joint channel estimation and detection algorithm for MIMO channels
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.
