Discrete Hartley matrix transform precoding-based OFDM system to reduce the high PAPR
ICT Express, 2019 The high peak-to-average power ratio (PAPR) is one of the major drawbacks of the orthogonal frequency division multiplexing (OFDM) systems that make non-linear distortion in practical implementation of high power amplifier (HPA).
