Bit Error Performance for Asynchronous DS/CDMA Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTHE)
In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multiple access interference (MAI) as an improved Gaussian process. The channel is modeled as a multipath flat Rayleigh fading channel. Numerical results are obtained by using the improved Gaussian approximation (IGA) and compared to the standard Gaussian approximation (SGA).
