WebAug 1, 2014 · An information-enhanced sparse binary matrix (IESBM) is proposed to improve the quality of the recovered ECG signal from compressed sensing. With the detection of the area of interest and the enhanced measurement model, the IESBM increases the information entropy of the compressed signal and preserves more … Webthe Orthogonal Optical Codes (OOC) and binary compressed sensing matrices. We also introduce deterministic bipolar m× n RIP fulfilling ±1 matrices of order k such that m ≤ O k(log2 n) log2k lnlog2k. The columns of these matrices are binary BCH code vectors where the zeros are replaced by −1. Since
Compressed sensing and reconstruction with bernoulli matrices
WebBinary compressed sensing (BCS, [1]) refers to com-pressed sensing (CS, [2]) in the case of sparse binary signals. We can mathematically formulate BCS as follows: recover the sparsest x2f0;1gnfrom y= Ax, given A2Rm;nwith m WebIt first discusses the compressive sampling model, FH-BPSK (frequency hopping binary phase-shiftkeying) modulation signal model and its sparsity. Then, it focuses on the RIP (Restricted Isometry Property) and incoherent properties of measurement matrix in digital domain compressive sampling, as well as noise folding caused by compressive sampling. darwin\\u0027s 5 principles of natural selection
