摘要
针对目前提出的多载波估计算法存在的速度与精度的问题,基于模糊控制理论,改进和完善了多载波信号载频估计算法。通过对多载波时隙ALOHA网络真实卫星信号的载频频点提取,验证了该改进算法的时效性。
An algorithm of multi-carrier frequency estimation is improved, and the multi-carrier frequency of time slot ALOHA network real satellite signal is extracted. The results indicate that the algorithm is a fast and accurate estimation algorithm of multi-carrier frequency.
