Abstract

In this paper, we propose a peak-power-suppression (PPS) scheme for a multi carrier transmission (MCT) system where subchannels are band-limited by filtering before the multiplexer. In this scheme, transmit pulse power before filtering is decreased whenever envelope-peak amplitude is above a given threshold level. A reduction of 75% in peak power is achieved with a little, but insignificant, degradation in BER performance by applying the PPS scheme to an MCT system with 8 subchannels under flat fading conditions. The proposed scheme is also investigated with an adaptive transmit power control, and average transmit power and peak-to-mean power ratio (PMPR) are reduced.
