摘　　要：提出了一种改进型的基于前向自适应方式的TR接收机结构,并对其性能进行了理论论证和仿真分析,证明该接收机在特定的信道模型下有着可以与完全Rake相差不大的BER性能,硬件实现复杂度低,而且其特殊的信号结构设计特别适合用于脉冲同步的导频信号的接收。In this paper, based on former work in this field, an improved adaptive and TR-based receiver is presented, followed by theoretic demonstration and simulations on its performance. Simulation comparisons among different receiver structures indicate that the receiver introduced by us, with a low complexity in hardware implementation, is able to guarantee BER comparative to Arake in given channel models. And what＇s more, the particular design of transmission signals makes it nearly tailored for the reception of pilot pulses for synchronization.
