用于模拟通信系统中不同统计信道场景下的服从不同分布的噪声。(Communication systems used to simulate different scenarios of statistical channel obey different distributions of noise.)

卫星通信信道链路参数计算与模拟.由于降雨对不同频段下的卫星通信造成不同的衰减，通过计算与模拟卫星通信信 道链路参数，可以设计出可靠性更高的卫星通信系统。(Satellite communication channel link parameter calculation and simulation. Due rainfall in different frequency bands for satellite communications under different attenuation caused by calculation and simulation of satellite communication channel link parameters, you can design a higher reliability of satellite communications systems.)

实现卷积编码和相应的维特比译码（卷积码编码器为（2，1，3），维特比译码针对第1、3位模二加和第1、2位模二加）(Convolutional coding and the corresponding realization of Viterbi decoding (convolutional code encoder for the (2,1,3), Viterbi decoder bit mode for the first 1,3 and 1,2 position two plus two plus model ))
