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 ...
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 ...
Localization of wireless sensor networks using multidimensional scaling
(University of Missouri--Columbia, 2007)
envision all potential applications. All these applications require knowing the locations of nodes, thus demanding a localization algorithm that is less complex in terms of computations, communication overhead and increasing the overall lifetime...
Multiuser TDMA channel estimation
(University of Missouri--Columbia, 2004)
side assumes perfect channel knowledge. In this thesis I have proposed a very computationally easy and efficient algorithm of joint channel estimation based on least squares. The channel for all the users is simultaneously estimated. For this pilot...
Mobile speed estimation for hierarchical wireless network
(University of Missouri--Columbia, 2005)
frequency noise and interference components. Specifically, the algorithm is tailored for EDGE system, and slot autocovariance function is introduced to avoid the slot burst frequency of EDGE system, which might affect the estimation accuracy. Both computer...
Channel modeling, estimation and equalization in wireless communication
(University of Missouri--Columbia, 2005)
is an optimum equalizer for all the case. However, due to its computational complexity, it is impractical for today technologies in third generation wireless communication. Thus, a suboptimum equalizer so-called perturbation equalizer is proposed, which...
Turbo equalization in wireless communication
(University of Missouri--Columbia, 2005)
computational complexity. Thus, the sub-optimum equalizers such as decision feedback equalizer (DFE) have to be considered. Due to the improvement of the system performance based on the conventional DFE algorithm is limited by the error propagation, a novel low...
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 ...
Single carrier frequency domain equalization for broadband wireless communications
(University of Missouri--Columbia, 2007)
computational complexity. Finally to enhance the reliability of signal reception, three different diversity schemes namely, Maximum Ratio Receive Combining, Space-time block coding and Space frequency block coding are discussed and implemented for SC-FDE system...
Optimum receiver design and performance analysis for wireless communication
(University of Missouri--Columbia, 2005)
-channel interference on system performance. The theoretical performance expressions presented in this dissertation provide a set of analytical tools for communication system design and evaluation. In addition, all of the analytical results presented...
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 ...
