基于MIMO的置换索引差分混沌移位键控技术研究
Research on MIMO-based substitution indexed differential chaotic shift keying technique
摘要
Abstract
In order to solve the problems of low BER performance and low transmission rate of traditional differential chaotic shift keying communication system,a MIMO-based replacement indexed differential chaotic shift keying communication scheme is proposed.The scheme adopts MIMO technique and designs a space-time packet coding scheme to improve the system BER performance.The sub-stitution indexing method is utilized to enhance the transmission rate of the system through substitution matrix transformation.The bit er-ror rate formula under additive Gaussian white noise channel is derived.Simulation results show that the proposed scheme,compared with the PI-DCSK system,possesses higher data rate and better BER performance.关键词
