The Study of Chaotic Spread Spectrum Code in Asynchronous DS-CDMA Communication System

摘要：

In order to study the multi-access and anti-noise performance of the chaotic spread spectrum code in the asynchronous DS-CDMA system, an iterated and L bit quantized method was adopted here to generate the digital Logistic and Tent spread code, and the generated code was compared and analyzed with the traditional Gold code here. Simulations show that chaotic spread code has good bit error rate and multiaccess interference suppression performance in the asynchronous CDMA system.
