Clipping-Noise Guided Sign-Selection for PAR Reduction in OFDM Systems
The peak-to-average power ratio (PAR) of orthogonal frequency division multiplexing (OFDM) systems can be reduced by using an optimal set of subcarrier signs. However, this sign se...

Soft Detection and Decoding of Clipped and Filtered COFDM Signals
— Clipping and filtering is an attractive method for the reduction of the PAPR of OFDM signals before transmission. However, the resulting distortion noise impacts the error rat...

A Detection Algorithm for Clipped OFDM Signals Using the IDFT-Matrix
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...

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...
