Abstract

This paper describes an equalization scheme of an inner chip disortion which is caused by multi-path fading on a multi-carrier CDMA system. The proposed equalization scheme uses Auto-regressive Process model (AR) and prediction parameters of AR are obtained by Recursive Least Square algorithm (RLS). Simulation results of the multi-carrier CDMA system using the inner chip equalizer clarified that BER is 1.1×10^-2 at 20 dB of Eb/NO under the condition of two multi-path fading environments of which delay time is 2μsec and 100 Hz of fading frequency. In the evaluation of system parameters of the multi-carrier CDMA, number of subchannels are 16, data rate is 32 kbps and spreading ratio is 16.
