Abstract


Orthogonal Frequency Division Multiplexing (OFDM) is a multicarrier system supporting high data rate transmission and generally requires no equalization at the receiver, making it simple and efficient. One of the challenging issues for OFDM system is its high Peak-to-Average Power Ratio (PAPR). The high PAPR in OFDM leads to the use of high power amplifiers (HPAs) of wide dynamic range, leading to high cost and low efficiency of these amplifiers. There are several techniques proposed in the literature to tackle this problem of high PAPR in OFDM. One of the commonly used techniques is Partial-Transmit-Sequence (PTS). Artificial Bee Colony (ABC) algorithm used in basic PTS has also been suggested in the literature. In this paper, a new modified ABC-PTS algorithm using Companding and Reed-Solomon coding is proposed, which offers more reduction in PAPR compared to ABC-PTS algorithm. The increased Bit Error Rate (BER) caused due to companding is reduced by using Reed-Solomon code.
