The Application of Pulse Shaping in CDMA Communication System Based on PSWF
Abstract: Proper pulse shaping is useful for reducing Multiple Access Interference (MAI) in CDMA system. In this paper, several prolate spheroidal wave functions (PSWF) are selected as the shaping pulses for CDMA communication system, further analyzed and compared with traditional pulses to improve system performance. Theoretical analysis and Matlab simulation results show that PSWF_4 and PSWF_3 which are proposed in our paper have better system performances compared with other traditional pulses in the power limited condition.
