摘要：
In order to decrease wireless channel's destructive effects and increase system performance in multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) system, channel state information (CSI) is required. CSI is obtained by using pilot based; blind and semi-blind channel estimation algorithms. Though blind algorithm has low system performance is preferred owing to its high bandwidth efficiency. In this study, MIMO-OFDM channel estimation performance is investigated by using two different frequency selective channels for a blind algorithm based on independent component analysis (ICA) and comb type pilot based algorithm. It is seen from the results that MIMO-OFDM channel estimation performance changes according to channels frequency selectivity's, and pilot based algorithm is not always given best results.
