【摘要】 本文分析了适用于时变系统的变遗忘因子最小二乘法的性能,并将这种算法应用于循环平稳信号,推导出了针对循环平稳信号的变遗忘因子算法的递推公式。仿真实验证明,新的算法不需要参考信号,有较强的跟踪能力和较小的均方误差,而且即使在信噪比较小的条件下仍能保持很好的性能,所以更利于在智能天线技术中的实时应用。更多还原

【Abstract】 In this paper,a variable forgetting factor RLS(VFF-RLS) algorithm and its application in cyclostationary signals environment are discussed.The equation and the performance of cyclostationary signal VFF-RLS(C-VFF-RES) algorithm are analyzed.The novel algorithm does not need reference signal.The simulation results show its track ability is superior and its mean square error is small.The performance of C-VFF-RLS algorithm is great even in low SNR environment.So the proposed algorithm has great benefit to application in smart antenna technique.更多还原
