摘要/Abstract

摘要：

为解决相互正交互补码集中序列数目受限及多载波码分多址（MC-CDMA）系统信号峰均功率比（PAPR）过高的问题，提出一类具有低列向量 PAPR 且参数渐进达到最优的非周期二元准互补序列集（QCSS）的构造。通过设计一类新的映射函数集，得到的参数渐进最优的非周期二元QCSS与已有二元QCSS相比具有更多的序列数目。并将正交Golay序列集作为初始矩阵，构造得到的非周期QCSS列向量为Golay序列，进而保证了其列向量PAPR不超过2。实验仿真结果表明，所构造的互补序列集可以有效地将时域MC-CDMA信号PAPR降低到3 dB，同时系统具有良好的误码率性能。

Abstract:

To solve the problem of limited number of sequences in the mutually orthogonal complementary code set and high peak-to-average power ratio (PAPR) in MC-CDMA system, a construction of asymptotically optimal a periodic binary QCSS with low column vector PAPR was proposed.The obtained QCSS with asymptotically optimal parameters had more sequences than the existing QCSS due to the designed mapping set.The QCSS based on the orthogonal Golay sequence set had column vector PAPR of at most 2.Experimental simulation results show that the constructed sequence sets can effectively reduce the time-domain MC-CDMA signal PAPR to 3 dB and have good bit error rate performance.

Key words: quasi-complementary sequence set, asymptotically optimal, peak-to-average power ratio, MC-CDMA
