WebJun 23, 2010 · Compressed sensing seeks to recover a sparse or compressible signal from a small number of linear and non-adaptive measurements. While most of the studies so far focus on the prominent Gaussian random measurements, we investigate the performances of matrices with Bernoulli distribution. As extensions of symmetric signs ensemble, … WebNov 18, 2024 · In this paper, we present a novel construction for deterministic CS matrices based on decimated Legendre sequences. As we know, Legendre sequence provides a binary sequence with ± 1 entries which initially seems ideal to use in the context of CS. However, in order to be able to use these sequences as rows or columns of a …
WebMar 20, 2024 · Sensing matrix design is among the essential keys for compressive sensing to efficiently reconstruct sparse signals. It has been demonstrated that sensing … WebThe field of compressed sensing which was first introduced in [1] and further in [2], [3], deals with reconstruction of a n×1 but k-sparse vectorxn×1 from its linear projections (ym×1) onto an m-dimensional (m ≪ n) space: ym×1 =Φm×nxn×1. The two main concerns in compressed sensing are 1) selecting the sampling matrix Φm×n and 2 ...

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.
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 ...
WebOct 1, 2024 · Another deterministic construction of the CS matrix was proposed in exploiting signal sparsity and binary sensing matrices. In this paper, we propose a new deterministic sensing matrix that exploits the orthogonality of Kasami codes. The idea is to improve the orthogonality of Kasami codes before using them as columns of the sensing matrix. song i need a friendWebmatrices for compressed sensing of natural images, the dif culty of ...
