Efficient Algorithms for PAPR Reduction in OFDM Transmitters Implemented using Fixed-Point DSPs
OFDM has a very high peak-to-average power ratio. This imposes stringent dynamic range requirements on the analog front-ends of the transmitter and receiver and, if a fixedpoint pr...

Optimal constellation distortion for PAR reduction in OFDM systems
Abstract—The high peak-to-average-power ratio (PAR) of Orthogonal Frequency Division Multiplexing (OFDM) transmission systems significantly reduces the power efficiency or perf...

Iterative Correction of Clipped and Filtered Spatially Multiplexed OFDM Signals
— Peak-to-Average Power Ratio (PAPR) reduction in multicarrier systems with multiple transmit and receive antennas is considered. One attractive method for reducing the PAPR is t...
