An Orthogonal Projection-Based Approach for PAR Reduction in OFDM
Overview High peak-to-average power ratio (PAR) of the transmitted signal is one of the limitations to using orthogonal frequency-division multiplexing (OFDM) systems. This paper presents a novel orthogonal projection-based partial transmit sequences approach that achieves significant PAR reduction at low redundancy. The proposed method is applicable to OFDM systems with a large number of subchannels. This paper also for the first time provides geometrical interpretation to combining in the well-known partial transmit sequences scheme.
