摘要
介绍了OFDM的多载波CDMA系统上行链路中的一种盲信道估计算法。通过分析接收端的信号,利用接受信号和已知扩频码的二阶统计性估计出目标用户的信道脉冲响应。最后的仿真结果表明,该算法比把目标用户以外的用户信息当作噪声的算法具有更好的性能。
In this paper the authors introduce a blind channel estimation algorithm of uplink for multicarrier CDMA system based on OFDM,then analyse the received signal and use the second order statistics of the received and the expected spreading sequence to estimate the channel impulse response. Simulation shows that this algorithm has a better performance than that in reference.
