Minimizing the peak-to-average power ratio of OFDM signals via convex optimization

  title={Minimizing the peak-to-average power ratio of OFDM signals via convex optimization},
  author={Alok Aggarwal and Teresa H. Y. Meng},
Efficient OFDM transmission has been limited by power amplifier (PA) non-linearity combined with OFDM’s high peak-to-average power ratio (PAPR). In this paper, we show that minimizing the PAPR of an OFDM signal, subject to constraints on allowable constellation error and out-of-band noise, can be formulated as a convex optimization problem. The globally optimal solution can be calculated with low complexity using known algorithms. A system model is proposed for transmitting OFDM signals with… CONTINUE READING
