Estimation technology is one of the key technologies in the Orthogonal Frequency Division Multiplexing(OFDM) system, and the Decision-Directed channel estimation algorithm is paid close attention because of the superiority of decreasing means square error(MSE) and bit error rate(BER). In this paper, a Decision-Directed channel estimation algorithm based on linear minimum mean square error(LMMSE) was proposed, and it is simulated in the white Gaussian noise channel and multipath Rayleigh channel… CONTINUE READING
