Abstract

The problem of delay estimation in DS/CDMA systems employing aperiodic spreading codes is considered. A blind procedure is proposed, which does not require the use of known training symbols nor does it rely on the knowledge of other users' signature waveforms. This procedure can be implemented recursively and has a computational complexity that is quadratic in the processing gain. Simulation results reveal that the proposed algorithm provides delay estimates with an error smaller than 10% of the CDMA system chip interval.

一种用于长码DS/CDMA系统的盲延迟估计算法
研究了采用非周期扩频码的DS/CDMA系统的时延估计问题。提出了一种不需要使用已知训练符号,也不依赖于其他用户签名波形的盲方法。该过程可以递归实现,其计算复杂度为处理增益的二次元。仿真结果表明,该算法提供的延迟估计误差小于CDMA系统芯片间隔的10%。
