摘要 SC-FDMA(Single Carrier Frequency Division Multiple Access)系统峰均功率比(Peak of Average Power Ratio,PARP)较低,但是频谱利用率也很低。LTE-A(LTE-Advanced)系统作为LTE的技术演进,其关键技术之一聚合载波技术,利用片段带宽,提高频谱利用率,但是多个成员载波的引入会造成峰均比增加的问题。文章介绍在LTE-A多载波系统中,利用上行参考信号传输边带信息、分量载波自然分块的特点,提出一种易于实现且复杂度较低的降低PAPR的改进部分选择序列(Partial Transmit Sequences,PTS)算法。
