Abstract :
In this paper, a novel chip shaping being used in a particular DS-CDMA was addressed. The chip shaping is created by superpositioning of N/2 carriers in a typical interferometry-pattern chip shaping. The particular DS-CDMA refers to a DS-CDMA whose users are separated into two groups with the maximum number of users in each group being N/2. The result shows that by considering the frequency diversity, over a fading channel, the overall performance can be improved in such a way that the same QoS in all user can be achieved.
