The Reducing and Processing Methods of Peak Power in OFDM Systems |
| |
Abstract: | In this paper, we review the degradation and processing methods of peak power in orthogonal frequency division multiplexing (OFDM) systems. Theses methods usually were divided into two groups: one is based on design of OFDM signal, including coding technique, phase rotating and clipping or amplitude limiting technique, and the other is based on the implement of high power amplifier. |

Keywords: | orthogonal frequency division multiplexing systems peak power average power |
