PAPR reduction of OFDM signals using convolutional codes

Abstract

In this paper, we reduce the peak to average power ratio in OFDM systems using selective mapping technique that employs convolutional codes to avoid the need for the transmission of side-information. Since convolutional codes are already being used as forward error correction (FEC) block set in broadcasting systems like DAB/DVB and networks like WLAN/WMAN, we shall follow the coding standards set in these systems and then use them to bring down the PAPR along with improving the BER.
