Joint optimization of PAPR reduction based on modified TR scheme for MIMO-OFDM radar

Abstract In this paper, we propose a joint optimization method to reduce peak-to-average power ratio (PAPR) for multiple-input multiple-output orthogonal frequency-division multiplexing (MIMO-OFDM) radar systems, based on the modified tone-reservation (TR) scheme which has sufficient degree of freedom to satisfy some special and meaningful waveform design criteria. In terms of applying independent or concurrent reserved subcarrier weights for transmit antennas, we provide two PAPR reduction schemes respectively, i.e., independent TR (ITR) and concurrent TR (CTR). It is demonstrated that the proposed joint optimization method can effectively reduce the PAPR to an acceptable threshold and is superior to the conventional methods. Note that the optimized OFDM waveforms for MIMO radar can avoid the grating-lobes in distance domain. Simulation results are presented to verify the derivations.
