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…
New Bounds for Binary and Ternary Overloaded CDMA
Sh. Dashmiz, P. Pad, F. Marvasti
In this paper, we study binary and ternary matrices that are used for CDMA applications that are injective on binary or ternary user vectors. In other words, in the absence of addi…
Errorless Codes for Over-loaded CDMA with Active User Detection
Pedram Pad, Mahdi Soltanolkotabi, Saeed Hadikhanlou +2
In this paper we introduce a new class of codes for over-loaded synchronous wireless CDMA systems which increases the number of users for a fixed number of chips without introducin…
