| Abstract | ||
| Orthogonal frequency division multiplexing (OFDM) has become a Popular modulation method in high-speed wireless communication systems due to its high data rates transmission capability and robustness against multipath fading effects. One of the major drawbacks of OFDIVI at the transmitter side is the high peak-to-average power ratio (PAPR) of the OFDM signal. In this paper, an algorithm is proposed to reduce the peak to average Power ratio of OFDM signal with large number of sub-carriers. This algorithm is based on lone reservation method. The computer simulation tests shoe that the suggested algorithm reduces the PAPR to a factor of S25 dB and needs less number of iterations as compared with the traditional tone reservation algorithm. | ||
