Localization of wireless sensor networks using multidimensional scaling
(University of Missouri--Columbia, 2007)
of the network with low life-cycle costs. In this thesis we give details of a simple mathematical technique, classical multidimensional scaling and how it solves the localization problem. This so called MDS-MAP algorithm is able to find the relative positions...
Mobile speed estimation for hierarchical wireless network
(University of Missouri--Columbia, 2005)
on the development of a mobile speed estimation algorithm for practical wireless information system. The statistical properties of different wireless propagation environments are analyzed based on their respective mathematical reference models. The analytical results...
Channel modeling, estimation and equalization in wireless communication
(University of Missouri--Columbia, 2005)
on this abstract model, the closed form and mathematical tractable formula is derived for space-time correlation function. The new function can be further simplified other known special cases....
Pilot symbol design for multiuser CDMA systems
(University of Missouri--Columbia, 2004)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the development of advanced processor architecture and better fabrication technologies of chips mobile devices have shrinked in size and improved ...
Cognitive radios: spectrum sensing issues
(University of Missouri--Columbia, 2007)
Cognitive Radio can smartly sense and adapts with the changing environment by altering its transmitting parameters, such as modulation, frequency, frame format etc. The main challenges with cognitive radios are that it ...
Optimum receiver design and performance analysis for wireless communication
(University of Missouri--Columbia, 2005)
This dissertation is devoted to the optimum receiver design and theoretical performance analysis of wireless communication systems operated over fading channels, and this objective is incarnated by means of design, analysis ...
Turbo equalization in wireless communication
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Intersymbol interference (ISI) is a major impairment in wireless communication and hence equalization is applied to combat such interference. In addition ...
Single carrier frequency domain equalization for broadband wireless communications
(University of Missouri--Columbia, 2007)

On the simulations of correlated nakagami-m fading channels using sum-of-sinusoids method
(University of Missouri--Columbia, 2006)
This research work discusses the generation of Nakagami-m fading samples from sum-of-sinusoids method in which Nakagami process is generated by taking square root of Gamma process. Gamma process itself can be realized using ...
Multiuser TDMA channel estimation
(University of Missouri--Columbia, 2004)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Wireless communication systems require efficient utilization of the limited available spectrum. There are various methods in which division of spectrum ...
Robust receiver design for RF communication and underwater acoustic communication
(University of Missouri--Columbia, 2010)
This dissertation includes two parts: robust receiver design for wireless radio frequency(RF) communication, and robust receiver design for underwater acoustic (UWA) communication. The methodology of study for the first ...
