沃尔什(Walsh)码的频谱特性分析

Spectrum characteristic analysis of Walsh code

对Walsh码的频谱特性进行了系统的分析,总结出了Walsh码在频域上的分布规律,给出了Walsh码的中心频率与频带宽度的确定方法,为利用Walsh码的频谱特性解决移动通信中的远近效应问题。

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.
