摘　　要：提出了一种新的跳时超宽带无线通信系统的接收机结构,这种接收机将天线分集和Rake接收相结合, 从而提高了系统对多用户干扰和多径衰落的抑制能力。理论分析和仿真结果表明,这种接收机的性能优于常规的Rake接收机。A novel receiver structure for TH-UWB wireless communication system was proposed. The improved receiver, combining the antenna diversity with Rake receiver, could enhance the ability to suppress the multi-user interference and multipath fading. Theoretic analysis and simulation results show that the proposed receiver can achieve better performance than the conventional Rake receiver.
