Abstract

Fading is a critical issue for the next generation of digital cellular system using DS-CDMA. The problem of reducing bit error rate (BER) in presence of multipath fading is addressed. A new method is proposed based on adaptive near-far resistant demodulation techniques. It can be modified to eliminate the detrimental effect of fading in the presence of power control. In addition this method will drastically reduce hardware complexity and increase cell capacity for a digital cellular system
