Iterative EM channel estimation for turbo-coded DS CDMA receiver under different communication scenarios
(Wichita State University, 2008-05)This thesis proposes a scheme of obtaining an estimate of channel coefficients and noise power spectral density (PSD) using iterative expectation maximization based on a turbo-coded code-division multiple-access (CDMA) ... -
Iterative LDPC CDMA receiver with EM estimation
(Wichita State University, 2007-07)This thesis proposed a scheme of obtaining an estimate of channel coefficient and noise power spectral density (PSD), using iterative expectation-maximization (EM) channel estimation, based on a low-density parity-check ... -
Iterative low-complexity multiuser detection and decoding for coded UWB systems
(2006-07)In general, ultra wideband (UWB) signals are transmitted using ~'eIYshort pulses m tiIae domain, thus promising very high data rates. In this thesis, a recei'ler structure is proposed for decoding multiuser information ... -
Jacobian based power flow model for distribution network
(Wichita State University, 2017-12)With the increase penetration of renewable energy sources (RES) at the distribution level, the possibility of having voltage abnormalities is high. The reason being is because of the intermittent nature of the renewable ... -
Jamming statistics-dependent frequency hopping
(IEEE, 2016)This paper studies a jamming statistics-dependent frequency-hopping (FH) pattern generation scheme. Most existing FH patterns are determined by two encryption keys: (a) one for FH in the frequency domain, and (b) the other ... -
Joining glass fiber layers using a functionalized carbon nanofiber entangled network
(Elsevier, 2012-12-05)As-received glass fiber layers are joined using a carboxylic acid-functionalized carbon nanofiber (OCNF) entangled network utilizing a solution filtering process. Optical and SEM images of the OCNF/glass fiber assembly ... -
Joint physical and link layer error control analysis for nanonetworks in the Terahertz band
(Springer International Publishing AG, 2016-05)Nanonetworks consist of nano-sized communicating devices which are able to perform simple tasks at the nanoscale. The limited capabilities of individual nanomachines and the Terahertz (THz) band channel behavior lead to ... -
A joint power adaptation and spectrum handoff scheme in mobile cognitive radio networks
(IEEE, 2015)Cognitive radio (CR) technology is regarded as a promising solution by enabling unlicensed users to exploit the licensed spectrum unused by the licensed user in an opportunistic manner. Since in a mobile CR network, if ... -
Joint time delay and frequency estimation without eigen-decomposition
(2009-05)In this letter, we addressed the problem of estimating the time delay and the frequencies of noisy sinusoidal signals received at two spatially separated sensors. We employ the Propagator Method (PM) in conjunction with ... -
Jointly optimized QoS-aware virtualization and routing in software defined networks
(Elsevier B.V., 2016-02-26)Software Defined Networks (SDNs) have been recognized as the next-generation networking paradigm that decouples the network control plane from the data forwarding plane. A logically centralized controller is responsible ... -

Kalman filter design for large-scale systems by using unified approach
(Wichita State University, 2013-05)In this thesis, a method of designing a Kalman filter for a linear, discrete-time, singularly perturbed stochastic system using the delta operator was introduced. This unified approach, which is based on the delta operator, ... -
Kalman-Bucy filters with singular correlated noises
(IEEE, 1989-06-21)This paper presents a solution to the singular linear minimum-vaviance estimation problem in the discrete time case. An expression for the transfer function of the Kalman-Bucy filter with nonsingular correlated noises is ...
