摘要
针对正交频分复用(OFDM)具有高峰均比的缺点,研究并提出了一种基于改进A率的能够有效降低系统峰均比的信号压缩扩张算法。仿真结果表明,与改进率压缩扩张法相比,能够更好地减小信号峰值,具有更好的系统误比特性能。
Because of the disadvantage on a high complexity Peak-to-Average Power Ratio （PAPR）,a reduction method of companding function based on improving A rate reported by literature has been studied and improved for orthogonal frequency division multiplexing （OFDM） systems. Simulation results demonstrate that, compared with improved traditional rate companding function, the new improved method can more effectively reduce the signals peak value, and has the better system Bit Error Rate （BER） performance.
