摘要: Sparse recovery aims to accurately recover the support of

sparse vector from a very limited number of noisy linear measurements. We propose a new algorithm: multipath least

squares (MLS). It preserves the elegance and practicality of multipath matching pursuit (MMP) and provides better performance than the orthogonal least squares (OLS) algorithm. In addition, we first establish the mutual coherence based sufficient condition of stably recovering sparse signals by solving the unconstrained

$\ell1-\ell_2$ minimization problem.
