对数字陆地移动通信邻道干扰的抑制方法

The New Method for Suppressing Interfering Signal of Near Channel in the Digital Land Mobile Communication

本文介绍了在陆地移动通信中的一种邻道干扰抑制方法。其主要原理是从接收信号中计算出不期望的邻道干扰信号,从接收信号中减去它。本文提供这种方法的实验结果,在瑞利衰落环境下,邻道干扰可衰减16分贝。

This paper presents a new method for suppressing interfering signals of near channel in the land mobile communication. The basic principle is computing the unexpected interfering signals of near channel from the receiving signals, then suppressing the interfering signals. The paper also provides the test result used this method. The interfering signals can be attenuated 16 dB in Rayleigh distribution.
