Abstract— We propose low-complexity equalizers for Alamouti space-time coded orthogonal frequency-division multiplexing (OFDM) systems in time- and frequency-selective channels, ...
— A new approach for the association of the well known turbo codes to modulation schemes is presented. This method is designed for flat fading channels. It presents the advantage...
— This paper considers the problem of finding the path with minimum (zero) worst possible number of errors in a network with V nodes where (1) some nodes are capable of correcti...
— As Internet computing gains speed, complexity and becomes ubiquitous, the need for precise and accurate time synchronization increases. In this paper, we present a characteriza...

— We consider a ring topology with limited or full switching capability as deployed in high bandwidth metro optical networks and develop a model to estimate the probability of bl...
