APPARATUS AND METHOD FOR RECONSTRUCTING SPARSE SIGNAL USING PARALLEL ORTHOGONAL MATCHING PURSUIT TECHNIQUE

摘要

A reconstruction apparatus and a reconstruction method for reconstructing a sparse signal in a reception signal are disclosed. The reconstruction apparatus and the reconstruction method reconstruct a sparse signal using an orthogonal matching technique, select a plurality of initial indexes of an orthogonal matching pursuit technique, and apply the orthogonal matching pursuit technique with respect to the plurality of selected initial indexes, respectively.
