Successive PAR Reduction in (MIMO) OFDM
A successive scheme for PAR reduction in (MIMO/ SISO) OFDM is presented, where K (parallel/consecutive) OFDM frames are treated jointly. Employing Reed

Cross-Entropy-Based Sign-Selection Algorithms for Peak-to-Average Power Ratio Reduction of OFDM Systems
Sign-selection uses a set of subcarrier signs to reduce the peak-to-average power ratio (PAR) of orthogonal-frequency-division multiplexing (OFDM). However, the computational compl...

An Adaptive-Scaling Tone Reservation Algorithm for PAR Reduction in OFDM Systems
— Existing tone-reservation algorithms (such as the controlled clipper algorithm) for OFDM require a number of iterations to ensure the reduction of Peak-to-Average Power Ratio (...

A Simple Modulation Code with Peak Power Reduction and Coding Gain
Abstract— In this paper, a simple modulation code called symbol insertion for band-limited single-carrier systems is proposed. This code can reduce the peak-to-average power rati...
