One major defect in orthogonal frequency division multiplexing systems is the high peak-to-average power ratio (PAPR) at the transmitter. The linear nonsymmetrical transform (LNST) technique, one of the companding transform (CT) techniques for PAPR reduction, offers excellent performance, but requires additional side information. In this paper, a new ‘root CT’ technique without additional side information is proposed, and it can reach a good trade-off between the PAPR reduction and the bit… CONTINUE READING
