Discrete RF power synthesis of OFDM signals with high efficiency at high peak to average power ratios

OFDM signals suffer from large peak to average power ratios (PAR.) forcing the RF power amplifier (PA) to operate inefficiently in backoff modes. This problem is hard to solve, especially when the RFPA comprises a single active device. We describe a technique of power synthesis using several discret...
