Overlapped X domain multiplexing(Ov XDM) is a promising encoding technique to obtain high spectral efficiency by utilizing Inter-Symbol Interference(ISI). However, the computational complexity of Maximum Likelihood Sequence Detection(MLSD) increases exponentially with the growth of spectral efficiency in Ov XDM, which is unbearable for practical implementations. This paper proposes an Ov TDM decoding method based on Recurrent Neural Network(RNN) to realize fast decoding of Ov TDM system, which has lower decoding complexity than the traditional fast decoding method. The paper derives the mathematical model of the Ov TDM decoder based on RNN and constructs the decoder model. And we compare the performance of the proposed decoding method with the MLSD algorithm and the Fano algorithm. It’s verified that the proposed decoding method exhibits a higher performance than the traditional fast decoding algorithm, especially for the scenarios of a high overlapped multiplexing coefficient.

针对传统粒子群算法面对较高维度参数整定问题时所表现出的寻优速度慢、易陷入局部最优解的问题,提出一种动态环形拓扑结构混合粒子群算法(DynRing-hfpso)。该算法以粒子群算法为基底,融合萤火虫算法的优点,通过定义选择逻辑使粒子在迭代过程中各自独立地交替进行全局搜索与局部探索,并以自适应的粒子速度与位置约束方法提高算法在迭代过程中信息的利用率。对粒子群拓扑结构进行改进,以动态多邻域环形拓扑结构提高搜索空间覆盖能力,均衡收敛速度。设置动态性能分析以及消融实验,验证算法中粒子分布质量与改进措施的有效性。采用分数阶比例-积分-微分(FOPIλDμ)控制下的速度伺服系统作为应用场景,将该算法与其他四种算法进行对比。结果表明,DynRing-hfpso算法较已有的元启发式优化算法有更快的收敛速度与更优的收敛精度,且在多次实验中展现出更强的鲁棒性。
