在选择映射(SLM)方法生成的待选序列基础上,提出了一种不需要增加IFFT次数,仅通过对待选序列的线性组合,构造出更多的新待选序列的多信号表示方法,以此提高SLM算法的性能。文中MSR方法的两种实现方案,经仿真实验结果表明,研究的算法能够有效地降低系统的PAPR。
Based on the candidate sequence generated in selecting mapping (SLM) method, this paper proposes a bind of multiple signals represent (MSR) method with can create new candidates via linear combination of those in SI.M and improve the performance of the conventional SLM withed more IFFTs. Two schemes to realize the MSR method are given in the paper. The simulation results verify that the MSR method is effective to reduec the system PAPR.
