为了降低广义频分复用系统存在着多载波系统中固有的高峰均功率比问题
本文提出了一种适用于广义频分复用系统的子载波抑制高峰均功率比算法。该算法以限幅法为基础
降低了系统的高峰均功率比
但与限幅法不同的是
该算法几乎不会对带外性能及误码率性能造成影响。由于子载波抑制高峰均功率比算法的峰均功率比抑制性能略差于限幅法
因此本文进一步提出将部分序列传输与子载波抑制高峰均功率比结合来进一步抑制系统高峰均功率比的算法。仿真表明: 本文提出的算法的高峰均功率比抑制性能与限幅法相同
且不会对系统的带外与误码率性能造成影响。
To reduce the inherent peak-to-average power ratio (PAPR) problem in a generalized frequency division multiplexing (GFDM) system
this study proposes the PAPR reduction subcarrier (PRSC) algorithm
which is suitable for the GFDM system. Building upon the clipping algorithm
the proposed algorithm reduces the PAPR of the GFDM system. Different from the clipping algorithm
the PRSC algorithm minimally affects out-of-band and bit error rate performance. As the PAPR suppression performance of the PRSC algorithm is slightly worse than that of the clipping algorithm
this study also proposes an algorithm that combines partial transmit sequence and PRSC to further reduce the PAPR of the system. The simulation results show that this combined algorithm achieves the same level of PAPR reduction as the clipping algorithm
and the out-of-band and bit error rate performance of the system are unaffected.
