The research of MIMO - OFDM has received much attention in the wireless communication system in the future. The channel estimation which estimates the channel response of time or frequency field,revises and recovers the data received is an important aspect to achieve the high transmission performance for MIMO - OFDM system. A lot of channel estimation algorithms are discussed fully and deeply on MIMO - OFDM systems. Analysis and comparison on no - blind channel estimation algorithms for LS and MMSE, blind channel estimation algorithms and semi- blind channel estimation algorithms are emphasize...
