Abstract:

正交时频空(Orthogonal Time Frequency Space,OTFS)调制技术和索引调制(Index Modulation,IM)技术适用于高移动性场景,具有高频谱效率等优势,在图像传输领域应用前景广泛.然而,结合索引调制的正交时频空(Orthogonal Time Frequency Space with Index Modulation,OTFS-IM)调制技术的算法实现复杂度较高.对此,在广义近似消息传递(Generalized Approximate Message Passing,GAMP)的基础上改进,提出一种基于概率排序的阻尼广义消息传递算法.实验结果表明,在图像传输应用中,与传统的最小均方误差结合最大似然方案(Minimum Mean Squared Error with Maximum Likelihood,MMSE-ML)相比,所提的算法具有更低的复杂度,性能也优于传统的MMSE-ML传输方案.
