Abstract
The great interest in UWB communications was sparked by FCC rulings
in February 2002 that authorized the unlicensed commercial deployment of
UWB technology under a strict power control in 7500 MHz of spectrum. This
fast-emerging technology uses extremely narrow and low-power RF pulses to
transmit and receive information. Using the short-duration pulses as the basic
building blocks of communication systems gives exceptionally attractive
features as well as unique technical challenge.
The objective of this research is to study and analyze the performance
of M-PAM and M-PPM UWB signals.
The thesis presents a comprehensive background of the UWB
technology. Short-pulse generation, UWB antennas, UWB modulation and
multiple-access techniques, as well as UWB applications and a comparative
analysis of UWB, narrowband, and spread-spectrum wideband
communication systems are discussed.
The methodology of this work is based on simulation of symbol error
probability using MATLAB programming language.
The symbol error probability is plotted for M equal to 2, 4, and 8 as a
function of Eb/No and it is found that for M-PPM signals, Performance
improves as M increases, while the opposite is true for M-PAM signal
