提出了一种评估异步DS-CDMA中脉冲整形和扩频序列统计联合效应的通用框架。在此基础上，分析了三种可能的脉冲形状（矩形、限带矩形和平方根提升余弦）与三种可能的扩频序列（i.i.d、混沌和最优）相关的影响。与传统系统相比，用户容量提高了16%。
A general framework to assess the joint effect of pulse shaping and spreading sequence statistics on asynchronous DS-CDMA is developed. With this, the effect of three possible pulse shapes (rectangle, band-limited rectangle, and square-root raised-cosine) associated with three possible spreading sequences (i.i.d., chaos-based, and optimum) is analyzed. Improvements up to 16% in users capacity are shown over traditional systems.
