摘要: |
目前正交频分复用(OFDM)正得到越来越广泛的应用,但其主要缺点是有较高的峰均比(PAPR),虽然有许多降低OFDM信号的峰均比的方案,但是却大大增加了系统的复杂性,本文通过改进一种降低OFDM信号峰均功率的方法,很好地解决了复杂性和峰均比的降低的问题。 |

() |
Abstract: |
OFDM is studied in many fields, but it has a problem of high PAPR. There are many methods to reduce the PAPR for OFDM, but these methods usually increase the complexity of OFDM system. In this paper, the authors propose a new concept of OFDM, and it can achieve the lower PAPR and complexity of system. |
