Deterministic Construction of Compressed Sensing Matrices using BCH Codes
Arash Amini, Farokh Marvasti
In this paper we introduce deterministic RIP fulfilling matrices of order such that . Th…
A Unified Approach to Sparse Signal Processing
F. Marvasti, A. Amini, F. Haddadi +6
A unified view of sparse signal processing is presented in tutorial form by bringing together various fields. For each of these fields, various algorithms and techniques, which hav…
OFDM Channel Estimation Based on Adaptive Thresholding for Sparse Signal Detection
Mahdi Soltanolkotabi, Arash Amini, Farokh Marvasti
Wireless OFDM channels can be approximated by a time varying filter with sparse time domain taps. Recent achievements in sparse signal processing such as compressed sensing have fa…
Limits of Deterministic Compressed Sensing Considering Arbitrary Orthonormal Basis for Sparsity
Arash Amini, Farokh Marvasti
It is previously shown that proper random linear samples of a finite discrete signal (vector) which has a sparse representation in an orthonormal basis make it possible (with proba…
High-dimensional analysis of semidefinite relaxations for sparse principal components
Arash A. Amini, Martin J. Wainwright
Principal component analysis (PCA) is a classical method for dimensionality reduction based on extracting the dominant eigenvectors of the sample covariance matrix. However, PCA is…
