Peak-to-Average-Power Ratio Reduction Using Low-Complexity MIMO SFBC CIOFDM System
This paper presents MIMO SFBC CIOFDM on two-transmit and two-receive antennas. First, STBCDPC is used for avoiding interference and improving the transmitter diversity. Next STBCDPC with modulo operation i.e TomlinsonHarashima precoding (THP) is proposed to reduce peak-to-average-power ratio. In narrow band interference channel MIMO SFBC CIOFDM achieves considerable BER improvement. Compared with STBCDPC/THP technique, the proposed MIMO SFBC CIOFDM can provide low PAPR and excellent BER performance.
