摘要 提出了一种新的用于减小OFDM信号峰均功率比的压缩扩张技术,通过与改进的压缩扩张技术的对比,详细介绍了新方法并分析了对PAPR的改善程度及其用于OFDM系统时对系统误比特率的改善等性能。实验仿真结果说明,新的非线性压缩扩张技术可以获得更为高效的系统性能增益。 A novel companding transform scheme is proposed to reduced the Peak-to-Average Ratio of Orthogonal Frequency Division Multiplexing signals,compared with the improved companding scheme,the proposed scheme is illustrated in detail and analyzed in terms of reducing PAPR and improvement in BER performance in OFDM system.The simulation results confirm that the suggested scheme can outperform the improved companding scheme substantially.
