| Abstract(in English) | Transmit filtering, transmit equalization, precoding, or power allocation possibly 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 selective 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. Motivated by the fact that a "bad" arrangement of modulated symbols in a transmission block leads to high peak power, we introduce phase rotation in time domain. In this paper, we 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 square-root Nyquist filtered SC-FDE, joint Tx/Rx SC-FDE, and those transmission schemes with FD-SLM. |
