Intercarrier interference self-cancellation for space-time-frequency MIMO-OFDM system

Orthogonal frequency division multiplexing (OFDM) is proven a successful technique in wireless communication system which is sensitive to carrier frequency offset (CFO). The effect of CFO introduces intercarrier interference (ICI) to OFDM system. The purpose of this paper is to reduce ICI using ICI self-cancellation in MIMO-OFDM system by data allocation in space-time-frequency (STF). This paper also presents data allocation of complex pair to reduce peak-to-average power ratio (PAPR). Simulations by comparing STF MIMO-OFDM with conventional OFDM show an optimistic result especially at a high Eb/No.
