Performance evaluation of blind equalization techniques in the digital cellular environment
Title
Performance evaluation of blind equalization techniques in the digital cellular environment.
Creator
Boccuzzi, Joseph., Florida Atlantic University, Sudhakar, Raghavan
Abstract/Description
This thesis presents simulation results evaluating the performance of blind equalization techniques in the Digital Cellular environment. A new method of a simple zero memory non-linear detector for complex signals is presented for various forms of Fractionally Spaced Equalizers (FSE). Initial simulations are conducted with Binary Phase Shift Keying (BPSK) to study the characteristics of FSEs. The simulations are then extended to complex case via $\pi/$4-Differential Quaterny Phase Shift...
Show moreThis thesis presents simulation results evaluating the performance of blind equalization techniques in the Digital Cellular environment. A new method of a simple zero memory non-linear detector for complex signals is presented for various forms of Fractionally Spaced Equalizers (FSE). Initial simulations are conducted with Binary Phase Shift Keying (BPSK) to study the characteristics of FSEs. The simulations are then extended to complex case via $\pi/$4-Differential Quaterny Phase Shift Keying ($\pi/$4-DQPSK) modulation. The primary focus in this thesis is the performance of this complex case when operating in Additive White Gaussian Noise (AWGN) and Rayleigh Multipath Fading channels.

Comparison of different realizations and adaptive algorithms for channel equalization
Title
Comparison of different realizations and adaptive algorithms for channel equalization.
Creator
Kamath, Anuradha K., Florida Atlantic University, Sudhakar, Raghavan, College of Engineering and Computer Science, Department of Computer and Electrical Engineering and Computer Science
Abstract/Description
This thesis presents simulation results comparing the performance of different realizations and adaptive algorithms for channel equalization. An attempt is made to study and compare the performance of some filter structures used as an equalizer in fast data transmission over the baseband channel. To this end, simulation experiments are performed using minimum and non minimum phase channel models with adaptation algorithms such as the least mean square (LMS) and recursive least square (RLS)...
Show moreThis thesis presents simulation results comparing the performance of different realizations and adaptive algorithms for channel equalization. An attempt is made to study and compare the performance of some filter structures used as an equalizer in fast data transmission over the baseband channel. To this end, simulation experiments are performed using minimum and non minimum phase channel models with adaptation algorithms such as the least mean square (LMS) and recursive least square (RLS) algorithms, filter structures such as the lattice and transversal filters and the input signals such as the binary phase shift keyed (BPSK) and quadrature phase shift keyed (QPSK) signals. Based on the simulation studies, conclusions are drawn regarding the performance of various adaptation algorithms.
