文章根据频率选择性衰落信道的抽头延迟线模型，将针对平坦衰落信道的CS(周期平稳过程理论)频偏盲估计

算法扩展到了频率选择性衰落信道，并通过仿真证明这种扩展是可行的.仿真结果还表明CS算法不仅有好的抗平

坦衰落能力，而且有很好的杭频率选择性衰落性能.-Article according to frequency selective fading channel tap delay line model, the flat fading channel for CS (cycle stationary process theory) Frequency Offset Estimation Algorithm extended to frequency selective fading channel, and simulation prove that expansion is feasible. Simulation The results also show that the CS algorithm not only has good ability of anti-flat fading, and have a good hang frequency selective fading performance.
