基于Simulink的直接序列扩频通信系统仿真设计
Design of direct sequence spread spectrum communication system based on Simulink
摘要
Abstract
The visual simulation tool Simulink provided by Matlab is used to build a simulation model of direct sequence spread spectrum communication system. The simulation design of transmitter module and receiver module of direct sequence spread spectrum communication system was carried out with Simulink. The relationship among BER,SNR and spreading gain of DSSS system was researched by means of every waveform and spectrum transformation diagram in the transmission process. The simulation model was tested under the given simulation conditions. The results show that the system has high SNR,good perfor-mance and constant bit error rate;and the signal-to-noise ratio at the output end can be improved if the spread gain of the direct sequence spread spectrum communication systems is increased.关键词
