Abstract

In this paper, an adaptive parallel interference cancellation (PIC) scheme is proposed for the asynchronous multicarrier direct sequence code division multiple access (MC-DS-CDM A) system. An adaptive MAI estimation algorithm is applied before the PIC stage to improve the accuracy of the MAI cancellation. The performance behaviour of our proposed detector is investigated and its analytic hit error probability is derived. The theoretical results agreed well with the simulations. It is shown that the adaptive PIC receiver outperforms the matched filter and the conventional PIC receiver for the MC-DS-CDMA system in a fading channel.
