Abstract :
In this paper, we compare the performance of two peak-to-average power ratio (PAPR) reduction schemes. Specifically, selected mapping (SLM) and partial transmit sequence (PTS) schemes are investigated. The analysis was performed for an OFDM system aligned with the IEEE 802.16e standard with 256 and 1024 subcarriers. The results indicate that SLM has superior performance over PTS in reducing PAPR for the same number of subcarriers but at the expense of higher computational complexity. We have also investigated a modified selected mapping scheme with lower complexity.
