漏泄波导通信系统的噪声分析

Noise Analysis of Leakage Coaxial Cable Communication System

分析了由漏泄波导、中继放大器的级联网络和机车移动通信电台组成的系统在不同的工作方式时的噪声。并根据系统的参数计算了基台发—车台收、车台发—基台收的噪声和信噪比。计算结果与实际测试情况符合。

In this paper,the noise of the system which is composed of the vehicle mobile radio station and the cascaded network of leakage coaxial cable and repeater amplifiers is analyzed in different working mode.According to the parameters of the system,we also calculate the noise and the signal noise ratio in the case of the base station transmit—vehicle station receive and the vehicle station transmit—base station receive.The result of calculation coincide with the result of test.
