On the Performance of Sparse Recovery via L_p-minimization (0<=p <=1)
Meng Wang, Weiyu Xu, Ao Tang
It is known that a high-dimensional sparse vector x* in R^n can be recovered from low-dimensional measurements y= A^{m*n} x* (m<n) . In this paper, we investigate the recovering ab…

The Limits of Error Correction with lp Decoding
Meng Wang, Weiyu Xu, Ao Tang
An unknown vector f in R^n can be recovered from corrupted measurements y = Af + e where A^(m*n)(m>n) is the coding matrix if the unknown error vector e is sparse. We investigate t…

A Unique "Nonnegative" Solution to an Underdetermined System: from Vectors to Matrices
Meng Wang, Weiyu Xu, Ao Tang
This paper investigates the uniqueness of a nonnegative vector solution and the uniqueness of a positive semidefinite matrix solution to underdetermined linear systems. A vector so…
