A COMPUTATIONAL EFFICIENT DATA DETECTION METHOD FOR DOWNLINK OF AN MC-CDMA SYSTEM

Year 2017, Volume: 17 Issue: 2, 3497 - 3501, 27.07.2017

Abstract

In this paper, an Expectation-Maximization
(EM) based iterative data detection method for downlink of a multicarrier
system is proposed. The proposed method has low computational cost when
compared with the other iterative ones since it does not require any matrix
inversion if the requirements on users’ data are met. The performance of  the resulting algorithm is compared with
Minimum Mean Squared Error (MMSE) estimator in terms of Symbol Error Rate (SER)
for downlink of a Multi Carrier-Code Division Multiple Access (MC-CDMA) system in
the presence of frequency selective channels using computer simulations. It is
illustrated that the proposed algorithm outperforms the MMSE.
