Binary matrices for compressed sensing
WebSupport Recovery in Universal One-bit Compressed Sensing ... 1.1 Key difference from group testing, binary matrices, and technical motiva-tion Support recovery in the 1bCS problem has some similarity/connection with the combinatorial group testing problem [7]. In group testing, the original signal x is binary (has only 0s and 1s), and the WebExamples of deterministic matrices include Toeplitz , Circulant , and Binary BCH. In this paper, we focus on other attractive types of sensing matrices for compressive sensing called chaotic sensing matrices. This category of matrices provides the advantages of both random and deterministic matrices. Chaotic system produces a pseudo-random ...
