In this paper, we propose a novel blind equalization approach based on radial basis function (RBF) neural networks. By exploiting the short-term predictability of the system input, a RBF neural net is used to predict the inverse filter output. It is shown here that when the prediction error of the RBF neural net is minimized, the coefficients of the inverse(More)
Collaborative Product Development (CPD) is an engineering process that involves decision-making through iterative communication and coordination among product designers throughout the lifecycle of the product. The high level of collaboration and communication of a CPD environment requires a robust Distributed Information System. In this paper, we review(More)
We consider a broadcast erasure channel where a single transmitter broadcasts to M receivers, where the channel between the transmitter and each receiver is an independent erasure channel with success probabilities q = (q<sub>1</sub>, ..., q<sub>M</sub>). Prior work on this model by Cogill, Shrader and Ephremides (2011) established bounds on the expected(More)
This paper concerns the nonfragile guaranteed cost control problem for a class of nonlinear discrete-time dynamic systems with time-varying state delay and controller gain perturbations. The problem is to design a memoryless state feedback control law such that the closed-loop system is asymptotically stable and the closed-loop cost function value is not(More)
Due to the dynamic and multihop nature of the mobile ad-hoc network (MANET), voice communication over MANET may encounter many challenges. We set up a subjective quality evaluation model using ITU-T E-model with extension. And through simulation in NS-2, we evaluate how the following factors impact voice quality in MANET: the number of hops, the number of(More)
This paper studies the guaranteed cost control problem for a class of nonlinear discrete-time uncertain systems with state delay and a given quadratic cost function. The problem is to design a memoryless state feedback control law such that the closed-loop system is asymptotically stable and the closed-loop cost function value is not more than a specified(More)
A novel pulse design method for ultra wideband (UWB) communication is presented. The Gaussian pulses with the diverse variance factors are randomly selected as basis functions. The corresponding power spectral density (PSD) of linear combination pulse which complies with Federal Communications Commission (FCC) regulation is obtained by adjusting the(More)
