Cooperative transmission, where spatially distributed users form a multi-antenna system and assist in forwarding the information from source to destination node, achieves the diversity gain of a mu

Multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) combined with time division multiplexing (OFDM/TDM) based on frequency domain equalization (FDE) has been pro

In this paper, we theoretically analyze the achievable physical layer performance of multiple-domain diversity mechanism in wireline home networks, where the content is either kept within the same

Two-sided communication switching networks with an equal number of input and output terminals (N) have been looked upon as permutation generators of order N.1'2 Alteration of the permutation being

We analyze and solve a game in which a player chooses which of several Markov chains to advance, with the object of minimizing the expected time (or cost) for one of the chains to reach a target st

A linear code can be thought of as a vector matroid represented by the columns of code's generator matrix; a well-known result in this context is Greene's theorem on a connection of the weight poly

We construct local piecewise polynomial dual bases for standard Lagrange finite element spaces which themselves provide maximal polynomial reproduction.

With increasing interest in energy constrained multi-hop wireless networks [2], a fundamental problem is one of determining energy efficient communication strategies over these multi-hop networks.

Recently, it has been shown that spectral optimization in copper access networks can significantly reduce the transmit power required, resulting in significant reductions in the line driver power c

This paper is concerned with the problem of estimating the current value, Xn, of a discrete-time stationary stochastic process given the k previous values, X,,-u Xn-2, · · ·, Xn-k.
