Peak-cancellation is a pre-distortion technique for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. The distortion introduced to the transmitted signals can be mitigated on the condition that the signal attenuation factor is known at the receiver. In this paper, to alleviate the distortion and disclose the signal feature of peak-cancellation...
Multiple signal representation (MSR) is a class of distortionless method for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) system. However, MSR requires extra side information (SI) for informing the receiver the index of the transmitted signal. As results, the transmission efficiency is influenced. In this letter, a revised SI structure is designed...
This paper presents a low complexity peak-to-average power ratio (PAPR) reduction technique in interleaved orthogonal frequency-division multiple access (OFDMA) system. The basic idea is to explore the special structure of interleaved OFDMA so as to reduce the computational complexity for PAPR reduction. Current PAPR reduction techniques can be combined with the proposed structure, and repeated clipping...
