Abstract :
Differential frequency hopping (DFH) is a novel technique for the frequency-hopping system in HF (high frequency) bands. The frequency transition function (FTF) and the signal detection methods are the key issues for DFH system. A novel non-coherent detection scheme is proposed in asynchronous multi-user environments over Rayleigh-fading channels. With this novel detection scheme, the asynchronous multi-user performance of DFH is analyzed and validated by simulation. The results of analyses and simulations prove that the performance of asynchronous multi-user DFH system outperform that of synchronous multi-user DFH system over Rayleigh-fading channel, and the novel detection scheme can achieve better performance than the conventional non-coherent detection scheme in asynchronous multi-user environments
