| 摘 要： | 基于IEEE802.15.3a的UWB信道模型,采用BPSK调制研究了UWB系统中使用Pre-Rake合并方法的接收性能。Pre-Rake合并接收机不仅具有较低复杂度,而且可以有效地克服码间干扰。仿真结果表明,在CM1,CM2,CM3,CM4任意一种信道环境下,随着传输速率的提高,Pre-Rake的接收性能明显高于传统Rake接收机。

| Abstract: | Performance of a Pre-Rake combining receiver for a BPSK modulation UWB system was studied in a realistic channel mode proposed by IEEE 802.15.3a task group.This Pre-Rake combining receiver not only possesses low structure complexity but also can largely decrease the effect of inter-symbol interference(ISI).Simulation results indicate that in each of the four channel circumstance(CM1,CM2,CM3,CM4),this Pre-Rake combining receiver performs better than the conventional Rake receiver under higher transmission bit rate. |
