Abstract
In this paper, we investigate the performance of downlink multicarrier CDMA systems with differential modulation methods in multipath fading environments by analytical and simulation tools. Compared with basic coherent detection methods, the numerical results show that differential modulation provides robust performance and can actually result in competitive performance in cases where the channel estimation error in coherent detection is significant. Especially, with fast fading channels, differential modulation and detection could be viable alternative to coherent modulation, resulting in reduced implementation complexity and reduced pilot overhead.
