Sparse Channel Estimation by Factor Graphs
Rad Niazadeh, Masoud Babaie-Zadeh, Christian Jutten
The problem of estimating a sparse channel, i.e. a channel with a few non-zero taps, appears in various areas of communications. Recently, we have developed an algorithm based on i…
Implementation and optimization of Wavelet modulation in Additive Gaussian channels
Rad Niazadeh, Sahar Nassirpour, Mohammad B. Shamsollahi
In this paper, we investigate the implementation of wavelet modulation (WM) in a digital communication system and propose novel methods to improve its performance. We will put part…
A Unified Approach to Online Allocation Algorithms via Randomized Dual Fitting
Rad Niazadeh, Robert D. Kleinberg
We present a unified framework for designing and analyzing algorithms for online budgeted allocation problems (including online matching) and their generalization, the Online Gener…
