Abstract

In this paper we present a solution for improving performance of orthogonal frequency division multiplexing (OFDM) based simple cooperative relaying which is used for achieving 4th order diversity. The proposed scheme is compared with OFDM based simple cooperative relaying scheme with virtual orthogonal space time block coding (OSTBC). Each of these two schemes includes one base station with two antennas, two relay stations with a single antenna and one mobile station with a single antenna. The aim of the proposed solution is to improve bit error rate (BER) performance and code rate of the OFDM based cooperative scheme with virtual OSTBC. It is shown that the proposed scheme obviously outperforms performance of simple cooperative relaying schemes with virtual OSTBC.
