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 and additive white Gaussian noise (AWGN) channels. The multi-user performance of DFH with this novel receiver is studied analytically and validated by simulation results. By comparing of synchronous multi-user system and asynchronous multi-user system with conventional non-coherent detection receiver, it is shown that the performance of asynchronous multi-user system outperform that of synchronous multi-user system, and the novel detection scheme can achieve better performance than the conventional non-coherent detection scheme in asynchronous multi-user environments
