Lili Guo · Harbin Gongcheng Daxue Xuebao/Journal of Harbin Engineering University · 2003
With the spectrum characteristics of Walsh code systematically analyzed, and the distribution rules of Walsh code in frequency domain summarized,a simple method is established to determine the central frequency and frequency band of Walsh code.With this paper it is available to choose suitable Walsh code according to the known frequency structure. Walsh code have practical used to solve some problems such as the near-far effect in the mobile communication and narrow band interference in the communication counter.
