摘要

在异步环境下，扩频签名的产生是CDMA通信系统的主要问题之一。本文证明了扩频信号的频谱设计可以产生具有吸引人的互相关特性的高效限带信号。在类似gsm的多径环境中模拟了所提出的扩频信号的行为，并与使用Walsh二值序列的传统DS-CDMA进行了比较。

Spectral spreading signals for asynchronous CDMA

In asynchronous environments, the spreading signature generation is one of the main issues for CDMA communication systems. In this paper it is shown that the spectral design of the spreading signature leads to efficient band-limited signals with attractive cross-correlation properties. The behavior of the proposed spreading signals is simulated in a GSM-like multipath environment and it is compared to that of a traditional DS-CDMA using Walsh binary sequences.
