Abstract :Orthogonal frequency division multiplex insert ignore into journalissuearticles values(OFDM); is one of the best approaches to overcome frequency selectivity of channels. In multiple-input multiple-output insert ignore into journalissuearticles values(MIMO); orthogonal frequency division multiplexing insert ignore into journalissuearticles values(OFDM); systems, we purposed channel estimation with least squares insert ignore into journalissuearticles values(LS); estimation method in this paper. To improve channel estimation achievement a LS algorithm is developed, so we obtain Bit Error Rate insert ignore into journalissuearticles values(BER); performance of channel. Mean Square Error insert ignore into journalissuearticles values(MSE); of LS estimation calculated and depicted with figures. Signal to noise ratio insert ignore into journalissuearticles values(SNR); indicated notable efficacy in this paper that obtained by using the LS algorithm, in particular channels with variation in time.
