一种卷积与交织编码直扩系统的性能仿真
Performance Simulation of a Convolution and Interleaving Coding Based DSSS Communication System
摘要
Abstract
To analyze the performance of direct sequence spread spectrum communication system when different kinds of interleaving methods are integrated with convolution coding,a convolution coding and interleaving based error correction coding DSSS communication system is designed,and the system model is built in the Matlab/Simulink platform.Random interleaving and Matrix interleaving combined with general block interleaving are considered respectively in the AWGN channel condition.The simulation results indicate that as compared with uncoded DSSS communication system,the performance of convolutionally coded DSSS communication system in conjunction with two different interleaving methods designed in this paper is better when signal noise ratio is-1.35 dB or more.关键词
