The receiver uses L-fingered correlators, which are composed of RLS adaptive filters, to enhance the performance of multipath receiving. It can also track the amplitude of the received signal to form a real-time amplitude estimation which is correlated with the power of excess delay bin. The simulation results based on the IEEE UltraWide Band (UWB) channel models (CMl to CM4) show that the novel RLS algorithm can alter the attenuation estimation with the finger's power delay profile, and RAKE receiver with few fingers can be employed to get high performance.展开更多
