The Problems in Signal Detection of Multi-Band Spread Spectrum

Abstract:

Compared with the traditional direct sequence spread spectrum technology，Multi-band Spread Spectrum have great advantages. According to the basic principle of Multi-band Spread Spectrum, this paper Established the Multi-band Spread Spectrum system model, discusses the signal detection problems in terms of multi-band spread spectrum. Based on the results, it obtained the ruling methods of Gaussian white noise channel under multiple symbols detection and binary bits detection and likelihood ratio information theoretical expressions. And it finds that the two tests have the same mistake-symbol performance through the simulation. The experimental results show that multiple symbol detection and RS code used in conjunction with will achieve better performance.
