一种基于压缩感知的信号重建新算法
A New Signal Reconstruction Algorithm Based on Compressed Sensing
摘要
Abstract
Combined with the iterative method of generalized inverse, a new algorithm for sparse signal re-construction is developed based on linearized Bregman iteration for solving the basis pursuit problems. Dur-ing calculating Moore-Penrose generalized inverse, the algorithm only has the matrix-vector multiplication by iteration combined with its own,so that the singular value decomposition( SVD) is avoided. The numer-ical experiments show the computation time has reduced by about 2/3 than that of original algorithms. Meanwhile,the recovery of signals is stabe and effective. So this new algorithm is a feasible signal recon-struction algorithm.关键词
