Abstract :
A blind channel estimation algorithm of uplink is proposed in this paper by analyzing the received signal of uplink for MC-CDMA system. The proposed algorithm uses the second order statistics of the received and the expected spreading sequence to separate the user signal and to estimate the channel impulse response. The algorithm is easily implemented, the results of computer simulation show the proposed algorithm has excellent performance in different condition.
