Abstract

Transmit filtering, transmit equalization, precoding, or power allocation increases the peak-to-average power ratio (PAPR) of transmit single-carrier (SC) signal due to change in frequency-domain spectrum. Recently, we proposed a frequency-domain based selected mapping (FD-SLM) for suppressing the increased PAPR introduced by the transmit frequency-domain equalization (Tx-FDE). However, FD-SLM provides minor contribution when computational complexity is considered. In this paper, we are motivated by the fact that a 'bad' arrangement of modulated symbols in a transmission block leads to high peak power, and propose a time-domain phase rotation called time-domain SLM (TD-SLM). PAPR and BER performances when using the proposed TD-SLM are evaluated by computer simulation and are compared to conventional joint Tx/Rx SC-FDE and joint Tx/Rx SC-FDE with FD-SLM.
