摘要 在正交频分复用(orthogonalfrequencydivisionmultiplexing,OFDM)通信系统中,信道估计占有很重要的地位。论文提出了一种在OFDM信号循环保护前缀不足情况下也可应用的盲信道估计算法,它利用循环前缀信号结构采用子空间分解,计算简单。计算机仿真显示其有良好的性能。 Channel estimation is very important for OFDM (orthogonal frequency division multiplexing) communication system. A blind channel estimation algorithm which suits for OFDM signal with eigher sufficient or insufficient CP is proposed in this paper. The computer simulation results show that the presented algorithm has a good performance.
