摘要:In this paper, a layered channel estimation method is proposed for DS-UWB systems, where both ISI and IPI are taken into consideration. The multipath components are classified into layers with respect to their time delays and estimated layer-by-layer iteratively. In each layer, the ISI and IPI are mitigated by using the inherent characteristics of bipolar symbols and prior knowledge of the spreading code sequence and pilot symbols. A detection-directed refinement procedure is used to improve the estimation accuracy further. Simulation results show that the proposed scheme can be used to gain precise channel state information. © (2014) Trans Tech Publications, Switzerland.
