Optimal designs for space-time linear precoders and decoders
TLDR
We introduce a new paradigm for the design of transmitter space-time coding that we refer to as linear precoding. Expand
Product high-order ambiguity function for multicomponent polynomial-phase signal modeling
TLDR
Parameter estimation and performance analysis issues are studied for multicomponent polynomial-phase signals (PPSs) embedded in white Gaussian noise. Expand
Non-data-aided carrier offset estimators for OFDM with null subcarriers: identifiability, algorithms, and performance
TLDR
The ability of orthogonal frequency-division multiplexing systems to mitigate frequency-selective channels is impaired by the presence of carrier frequency offsets (CFOs). Expand
Optimal Linear Precoding Strategies for Wideband Noncooperative Systems Based on Game Theory—Part I: Nash Equilibria
TLDR
We propose a decentralized strategy, based on a game-theoretic formulation, to find out the optimal precoding/multiplexing matrices for a multipoint-to-multipoint communication system composed of a set of wideband links sharing the same physical resources, i.e., time and bandwidth. Expand
Joint Optimization of Radio and Computational Resources for Multicell Mobile-Edge Computing
TLDR
Migrating computational intensive tasks from mobile devices to more resourceful cloud servers is a promising technique to increase the computational capacity of mobile devices while saving their battery energy. Expand
Redundant filterbank precoders and equalizers. I. Unification and optimal designs
TLDR
Frequency-selective channels can be recovered even when deep fades are present with FIR zero-forcing equalizer filterbank precoders. Expand

TLDR
The aim of the paper is the performance evaluation of a method for the analysis of mono- or multicomponent linear-frequency modulation (LFM) signals, based on the Hough transform of the Wigner-Ville distribution of the signals. Expand
Filterbank Transceivers Optimizing Information Rate in Block Transmissions over Dispersive Channels
TLDR
Optimal finite impulse response (FIR) transmit and receive filterbanks are derived for block-based data transmissions over frequency-selective additive Gaussian noise by maximizing mutual information subject to a fixed transmit-power constraint. Expand
Competitive Design of Multiuser MIMO Systems Based on Game Theory: A Unified View
TLDR
This paper considers the noncooperative maximization of mutual information in the Gaussian interference channel in a fully distributed fashion via game theory and provides a unified view of the state-of- the-art results, showing that most of the techniques proposed in the literature to study the game, even though apparently different, can be unified using our recent interpretation of the waterfilling operator as a projection onto a proper polyhedral set.
