An Efficient FPGA Implementation of Orthogonal Matching Pursuit With Square-Root-Free QR Decomposition

Compressive sensing (CS) is a novel signal processing technology to reconstruct the sparse signal at sub-Nyquist rate. Orthogonal matching pursuit (OMP) is one of the most widely used signal reconstruction algorithms. However, the least square problem (LSP) in OMP algorithm limits its performance. T...
