• This letter studies the impact of chip waveform shaping on the multiple access interference (MAI) in band-limited direct sequence code-division multiple access (DS-CDMA) systems. The family of bandlimited waveforms with zero interchip interference (ICI) and with an excess bandwidth β in the range 0 ≤ β ≤ 1 is considered. A criterion for the performance comparison of various band-limited chip waveforms based on the elementary density function is established. The effect of varying the roll-off factor of a band-limited chip waveform on the MAI level is also investigated.
