一、引言 求伪码及其复码自相关函数的方法中,熟知的有概率法和解析计算法等,一般来说,用这些方法不能直接求出伪码及其复码的功率谱,而只能通过求自相关函数的富氏变换来间接地求出码的功率谱。
I. INTRODUCTION In the methods of seeking pseudo-code and its complex code autocorrelation function, there are well-known methods such as probabilistic method and analytic calculation method. Generally speaking, the power spectrum of pseudo-code and its complex code can not be obtained directly by these methods The power spectrum of the code can only be indirectly obtained by Fourier transformation of the autocorrelation function.
