频率选择性衰落信道中的频偏盲估计

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,而且有很好的抗频率选择性衰落性能.

Frequency offset blind estimation over frequency-selective fading channels

This paper employs the tapped delay line channel model for frequency-selective fading channels to extend a frequency offset blind estimation algorithm based on cyclostationary, which is proposed for flat fading channels, to frequency-selective fading channels. Simulations proves the feasibility of this extension. The simulation results also show that the CS algorithm can resist effectively to flat fading and frequency-selective fading as well.
