Modeling of Visible Light Channels and Performance Analysis of ACO-OFDM
(IEEE, 2015)
Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ...
Rapidly Time-Varying Channel Estimation for Full-Duplex Amplify-and-Forward One-Way Relay Networks
(IEEE-INST Electrical Electronics Engineers Inc, 2018)
Estimation of both cascaded and residual self-interference (RSI) channels and a new training frame structure are considered for full-duplex (FD) amplify-and-forward (AF) one-way relay networks with rapidly time-varying ...
Joint Channel Estimation Equalization and Data Detection for OFDM Systems in the Presence of Very High Mobility
(IEEE-INST Electrical Electronics Engineers Inc, 2010)
This paper is concerned with the challenging and timely problem of joint channel estimation equalization and data detection for uplink orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency ...
Nondata-aided joint channel estimation and equalization for OFDM systems in very rapidly varying mobile channels
(IEEE-INST Electrical Electronics Engineers Inc, 2012)
This paper is concerned with the challenging and timely problem of joint channel estimation and equalization for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very ...
Joint Channel Estimation and Equalization for OFDM based Broadband Communications in Rapidly Varying Mobile Channels
(IEEE, 2010)
This paper is concerned with the challenging and timely problem of channel estimation for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency selective and very rapidly time varying ...
Channel Estimation for Residual Self-Interference in Full-Duplex Amplify-and-Forward Two-Way Relays
(IEEE-INST Electrical Electronics Engineers Inc, 2017)
Training schemes for full duplex two-way relays are investigated. We propose a novel one-block training scheme with a maximum likelihood estimator to estimate the channels between the nodes as well as the residual ...
Bayesian estimation of discrete-time cellular neural network coefficients
(TUBITAK Scientific & Technical Research Council Turkey, 2017)
A new method for finding the network coefficients of a discrete-time cellular neural network (DTCNN) is proposed. This new method uses a probabilistic approach that itself uses Bayesian learning to estimate the network ...
Scaling Laws For Distributed Estimation Over Orthogonal Fading Channels
(IEEE, 2009)
We analyze the outage for distributed estimation over orthogonal fading channels as a function of the number of sensors K. We consider a scenario of fixed power per-sensor with an asymptotically large number of sensors. ...
Outage Diversity for Distributed Estimation over Parallel Fading Channels
(IEEE, 2008)
In this paper we study the outage diversity in distributed estimation over parallel fading channels. We find tight upper and lower bounds on the diversity order and show that they are arbitrarily close under certain ...
Distributed estimation over parallel fading channels with channel estimation error
(IEEE, 2008)
We consider distributed estimation of a source observed by sensors in additive Gaussian noise where the sensors are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a ...
