Abstract

The performance of a PN code acquisition scheme is analyzed and simulated for a DS/CDMA overlay system where a CDMA user and a narrowband user coexist in the same frequency band. The narrowband user is modeled as a narrowband interference (NBI) located at a fraction of the CDMA user´s bandwidth. To suppress the NBI, an interference suppression filter is employed at the receiver frontend. From the simulation results, it is shown that the interference suppression filter is very effective for suppression of the NBI and rapid PN code acquisition in a DS/CDMA overlay environment. The analysis can be applied to practical situations for a DS/CDMA overlay environment
