基于截短平衡Gold码的超宽带多径信道下Rake接收机的性能分析

he choice of Time-hopping sequence is very important for UWB radio communication system, the sequence directly depends on the performance of the UWB radio system. In this paper, through the in-depth analysis of key indicators of truncate balance Gold codes, and use truncated balance Gold code instead of traditional Time-hopping code, analyses A-Rake, P-Rake and S-Rake receiver model under the standard channel model. The results indicate that truncated balance Gold code can reduce the capture time of spreading code and have lower Bit Error Rate (BER) than traditional Time-hopping code.
