In this paper, two novel adaptive spatial scattering modulation (ASSM) algorithms, namely unequal transmission probability-based ASSM (UTP-ASSM) and equal transmission probability-based ASSM (ETP-ASSM), are proposed to pursue a better tradeoff between the computational complexity and spectral efficiency. According to available channel state information, the proposed ASSM algorithms are conducted to compute the optimal numbers of scatters and the optimal modulation orders constrained by the maximal tolerable symbol error probability (SEP). In addition, the minimal tolerate value of the minimal tolerant signal-to-noise ratio and SEP threshold are computed with a given data rate requirement by the bisection algorithm. At the receiver, a new type of optimal maximum likelihood detector is proposed to enhance the SEP performance. Furthermore, the union upper bound on the SEP is derived and analyzed. In addition, the computational complexity and system performance of the ASSM schemes are analyzed. Simulation results demonstrate that the proposed ASSM algorithms yield a lower SEP than the conventional spatial scattering modulation at the same value of average data rate.

自适应空间散射调制
在本文中,提出了两种新的自适应空间散射调制 (ASSM) 算法,即基于不等传输概率的 ASSM (UTP-ASSM) 和基于等传输概率的 ASSM (ETP-ASSM),以在计算量之间寻求更好的权衡。复杂度和频谱效率。根据可用的信道状态信息,所提出的ASSM算法用于计算由最大可容忍符号错误概率(SEP)约束的最佳散射数和最佳调制阶数。此外,最小容忍信噪比的最小容忍值和 SEP 阈值是通过二分算法在给定数据速率要求下计算的。在接收端,提出了一种新型的最优最大似然检测器来提高 SEP 性能。此外,导出并分析了 SEP 的联合上限。此外,分析了ASSM方案的计算复杂度和系统性能。仿真结果表明,在相同的平均数据速率值下,所提出的 ASSM 算法产生比传统空间散射调制更低的 SEP。
