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. © 2004 IEEE.
