摘要
提出了一种有效降低正交频分复用信号峰均比的方法,它是基于格雷编码(golaycodes)、利用陪集分选改进的编码方法,大大减少了传统的降OFDM系统的峰均比计算复杂度。仿真结果表明新算法更好地降低了正交频分复用系统信号的峰均比。
In this article, we present an effective method to reduce the PAR (peak to average power ratio) of an OFDM signal. Using the coding method improved by the choice of accompany aggregate, the computational complexity of conventional method for reducing the PAR in OFDM system is reduced effectively. Simulation results show that the new algorithm reduces more effectively the PAR in OFDM system.
