Efficient Recovery Algorithm for Discrete Valued Sparse Signals Using an ADMM Approach

Autor: Nuno M. B. Souto, Hugo Andre Lopes

Publikováno v: IEEE Access, Vol 5, Pp 19562-19569 (2017)

Motivated by applications in wireless communications, in this paper we propose a reconstruction algorithm for sparse signals whose values are taken from a discrete set, using a limited number of noisy observations. Unlike conventional compressed sens

The design approach of pseudo-random discrete signals with fractional power-law angular modulation (FM/PM) is considered in the article. These signals as a discrete set of time values with the uniform sample spacing acquire the properties of pseudo-r

De-noising algorithms for the raised cosine pulse signal using the minimum-energy frame in the discrete signal space

Autor: Ying-hai XIE, Wei YANG, Ting-ting FAN

Publikováno v: Tongxin xuebao, Vol 33, Pp 44-51 (2012)

The de-noising algorithms were proposed for the raised cosine pulse signal using minimum-energy(wavelet) frame in the discrete signal space.For the given two minimum-energy frames,the decomposition coefficients of sampled sequence appeared significan
