A novel discrete artificial bee colony algorithm‐based partial transmit sequences (DisABC‐PTS) scheme is proposed to reduce peak‐to‐average power ratio (PAPR) of orthogonal frequency division multiplexing signals. Compared to ABC algorithm‐based PTS scheme (ABC‐PTS) proposed previously, the DisABC‐PTS scheme works directly in discrete space, which has a high computational efficiency. Simulation results indicate that DisABC‐PTS scheme can obtain lower PAPR than existing PTS schemes and has a low computational complexity.
