The Optimum SRAKE based RAKE-DFE Receiver for Carrier DS-UWB Systems

摘要：

The carrier direct-sequence spread based ultrawide-band (DS-UWB) is challenging for serious inter-symbol interference (ISI) problem, which is resulted from the dense multipath with a long root-mean-square (RMS) delay spread.We adopt a RAKE-decision feedback equalizer (RAKE-DFE) receiver in this paper to cancel the ISI. Different from the conventional selective RAKE (SRAKE), we proposed the optimum SRAKE for the receiver to select rays. The theoretical analysis and simulation results show that the proposed SRAKE scheme is the optimum, and the proposed receiver can get good performance, which is better than conventional SRAKE based RAKE-DFE receiver.
