Multipacket Reception in Wireless Ad Hoc Networks Based on CDMA and Polynomial Phase-modulating Sequences

摘要

Based on the polynomial phase-modulating sequences algorithm , this paper presents two schemes for the application of CDMA with polynomial phase signals to improve the signal separation performance. Simulation results illustrate the proposed approach have 1 ～ 3 dB improvement about signal-to-interference and noise ratio in most environment, compared with the PPS algorithm.
