摘要

在IEEE 802.15.3a多径衰落信道下，对采用广义正交(GO)序列的直接序列扩频(DS-SS)脉冲无线电(IR)超宽带(UWB)系统的性能进行了评估。在给出的信干涉比(SIR)表达式的基础上，利用高斯近似(GA)方法得到了误码率(BER)性能的数值计算结果。数值和仿真结果均表明，GO序列比PN序列和Walsh Hadamard序列表现出更好的性能。

Multiple Access Performance of Ultra-Wideband Systems Based on GO Sequences

In this paper, the performance of direct sequence spread-spectrum (DS-SS) impulse radio (IR) ultra-wideband (UWB) system employing generalized orthogonal (GO) sequences is evaluated under the IEEE 802.15.3a multipath fading channel. Based on the signal-to-interference ratio (SIR) expression provided, the numerical computation results of bit error rate (BER) performance are obtained by means of Gaussian approximation (GA) method. Both the numerical and simulation results provided reveal that GO sequences exhibit better performance than PN sequences and Walsh Hadamard sequences.
