摘要

研究了频谱高效分频复用(SEFDM)系统中利用主动星座扩展(ACE)降低峰均功率比的算法。考虑非线性功率放大器(PA)的影响，对系统的整体性能进行了研究。得到与最佳误码率(BER)性能相对应的ACE参数值。考虑了两种类型的放大器模型:固态功率放大器(SSPA)和行波管放大器(TWTA)。

The Effectiveness of Active Constellation Extension for PAPR Reduction in SEFDM Systems

In this paper the algorithm of Active Constellation Extension (ACE) for peak-to-average power ratio (PAPR) reduction in spectral efficient frequency division multiplexing (SEFDM) systems is considered. Overall system performance is investigated taking into account influence of non-linear power amplifier (PA). Values of ACE parameters corresponding to the best bit error rate (BER) performance are obtained. Two types of PA models are considered: solid state power amplifier (SSPA) and traveling-wave tube amplifier (TWTA).
