Some Considerations for Interference Suppression in Multi-Band Frequency Hopping UWB Communications
some considerations for interference suppression technologies in multi-band frequency hopping ultra-wideband communications are made. Based on this communication system, the novel coexisting interference detection algorithm is proposed in this paper. This new algorithm can be realized in low complexity and in comparatively low level sampling rate. With the estimation parameters provided by the new interference detection algorithm, the frequency hopping code generator can control code map to avoid the coexisting interference to other wireless victim in the same band. The mathematic analysis and computer simulation for this new algorithm are made. The simulation results show that the new algorithm can detect the coexisting interference effectively in low sampling rate. MB-FH UWB communication system can improve interference suppression performance evidently using this new interference detection algorithm combined with interference suppression measures.
