Peak-to-Average Power Ratio Reduction by Cross-Antenna Translation for SFBC MIMO-OFDM Systems

Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a promising modulation scheme for high performance broadband wireless communications. However, one major drawback of MIMO-OFDM is the high Peak-to-Average Power Ratio (PAPR) of the output signals. LatinoviA? et al. proposed a PAPR reduction method termed Polyphase Interleaving and Inversion (PII) for MIMO-OFDM systems under the use of the Space-Frequency Block Coding (SFBC). In this paper, the authors find more degrees of freedom can be utilized among the multiple antennas for the SFBC MIMO-OFDM systems.
