Abstract

In multiple input multiple output (MIMO) with orthogonal frequency division multiple access (OFDMA) system, intercarrier interference (ICI) is one of the major drawback in the system. This is due to the orthogonality of the subcarrier which has been destroyed by frequency offset (FO) and thus degrades the system performance. In order to overcome this problem, one-third intercarrier interference selfcancellation (ICI-SC) subcarrier mapping method with space time frequency block codes (STFBC) is proposed. Average power desired (APD) signal, ICI and carrier to interference ratio (CIR) are derived theoretically and the proposed signal is analyzed with other previous methods. As a result, it is proven that by choosing the suitable subcarrier mapping with ICI-SC method, MIMO-OFDMA system performance which affected by FO can be improved with maximum diversity order.
