摘要
利用晴天、降雨、降雪、多云等气象条件下卫星信道的模型,对信源编码、载波调制、载波解调、信源译码全过程进行计算机仿真,得出了不同气象条件下误码率与信噪比的关系图.
Using satellite commucation channel model under different weather conditions such as fine, raining, snowing, and cloudy, the whole process ulating, and resource ratio is obtained. interpretation was of communication resource coding, carrier wave modulating and demod- simulated. The relationship between error probability and signal noise ratio is obtained.
