一种改进的稀疏自适应压缩感知重构算法

Abstract

Abstract:

For the performance optimization of the greedy matching pursuit algorithm,the linear variable step forward-backward pursuit algorithm (LvsFBP) is proposed based on FBP,a two-stage sparsity adaptive greedy algorithm.LvsFBP adjusts the iteration step size adaptively which reduces operational costs while enhancing algorithm reconstruction accuracy.The simulation results show that LvsFBP offers the better performance of signal reconstruction.
