Peak-to-average power ratio mitigation in quasi-orthogonal space time block coded MIMO-OFDM systems using selective mapping.
conference contribution
posted on 2009-12-04, 09:08 authored by Faisal S. Alharbi, Jonathon ChambersA study of a peak-to-average power ratio (PAPR) reduction scheme for quasi-orthogonal spacetime
block coded multi-input multi-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems
based on selective mapping (SLM) is presented. The reduction technique is based upon combining the PAPRs of
the transmission blocks from four antennas and exploits the associated antenna diversity gain to mitigate errors
in the transmission of the side information (SI) necessary for SLM. Simulation studies are presented which
show the cumulative complementary distribution functions (CCDFs) with and without the combining scheme
and bit error rates of the overall system. Comparisons are made with single antenna and conventional OFDM
schemes.
