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…
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…
