Abstract

As a means of suppressing interference, this paper analyzes the effect of filtering and diversity on the bit error rate performance of a direct sequence code division multiple access (DS-CDMA) overlay system. The system is analyzed in terms of the interference-to-signal power, ratio of interference bandwidth to spread spectrum bandwidth, order of diversity, multipath intensity profile and number of users. The performance of the system with and without filters is compared. It is shown that the use of filtering and diversity results in performance improvement compared to a system without filtering or system without diversity or both.
