Abstract :
A novel blind channel estimation algorithm is proposed for the MIMO-OFDM system based on second-order-statistics. The main idea is to take advantage of the frequency transform and channel autocorrelation characteristics to reduce the computation and make it possible to accomplish the estimation in only one or two symbols. Results show that performance of this new method is promising.
