Multi-user performance analysis of differential frequency hopping system over Rayleigh-fading channel
摘要
Abstract
A novel non-coherent detection scheme for differential frequency hopping (DFH) system is proposed in asynchronous multi-user environments over Rayleigh-fading channels. The synchronous and asynchronous multi-user performances of DFH with the conventional detection scheme and this novel detection scheme are analyzed, respectively. The performance results are validated with simulation. The results of analyses and simulations prove two conclusions. Firstly, the performance of asynchronous multi-user DFH system overcomes that of synchronous multi-user DFH system over Rayleigh-fading channel. Secondly, the novel detection scheme can achieve better performance than the conventional non-coherent detection scheme in asynchronous multi-user environments.关键词
