Distributed basis pursuit

WebApr 3, 2012 · We propose a distributed algorithm for solving the optimization problem Basis Pursuit (BP). BP finds the least L1-norm solution of the underdetermined linear system Ax = b and is used, for example, in compressed sensing for reconstruction. Our algorithm solves BP on a distributed platform such as a sensor network, and is … WebIn the following, we will demonstrate the basis pursuit algorithm. The Matlab code for this demonstration, which usesASP, can be foundhere. Without noise perfect recovery is possible. Indeed, the left side of 1 shows a sparse xin the basis A= [I;T], where T is the discrete cosine transform. The right side of 1 shows Ax, clearly not a sparse signal.
