结合图论中的二部图思想,提出了一种基于非平衡扩展器的分布式压缩感知网络结构。同时设计了与该体系结构相对应的分布式算法。并将基于非平衡扩展器的分布式压缩感知网络应用于火场仿真实验,通过均方误差和信噪比分析,证明了该模型不仅在降低节点能耗方面效果良好,而且在有噪和无噪情况下都能保证信号重构的性能。
In this paper, Combined with bipartite graph thought in graph theory distributed compressive sensing network architecture based on unbalanced expander is proposed. Meanwhile we’ve designed the distributed algorithm corresponding with the architecture. And we apply the distributed compressive sensing network based on unbalanced expander to the fire ground simulation experiment, through analysis of the mean square error and signal-to-noise ratio, we prove the proposed model not only takes good effect on reducing nodes’ energy consumption but also ensuring the performance for the signal reconstruction in noisy and noise-free case.
