Parameter estimation is analyzed using two kinds of common sampling-type DFRFT(discrete fractional Fourier transform) algorithm. A model of parameter estimation is established. The factors which influence estimation a...
线性调频(Linear Frequency Modulation,LFM)干扰是一种典型的非平稳宽带干扰信号。分析了线性调频干扰对正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)系统性能的影响;为了降低LFM干扰对OFDM性能的影响,利用OFDM信号...
