Clipping and Quantization in Data Converters (pdf)
In this white paper we will show that the degradation induced
by A/D quantization and clipping noise in a DSP system is heavily
dependent on the signal level and signal type presented to the A/D
converter. Standard formulas for computing the degradation do not
include the signal level, nor do they account for clipping distortion.
The Effects of Timing Jitter on A/D Conversion (pdf)
One of the least understood aspects of A/D conversion is the impact
that jitter on the sampling clock has on the accuracy of the
conversion process. In this whitepaper we will show that the timing
jitter has a serious impact on quality of the the conversion process,
as well as discuss the effects of the spectrum of the jitter on
Probability Distributions (pdf)
This is a quick-reference guide to a few commonly used
probability distributions. The key properties of several
distributions are tabulated and the text contains brief
Computation of Rice and Noncentral Chi-Squared Probabilities
This report is a discussion of methods for computing the
generalized Marcum Q function. Included is a summary of
noncentral chi-squared and Rice random variables, some
properties of Marcum's Q function, a discussion of
inverting the Q function and details of the methods
themselves. A Bessel function series approach, Parl's
method, and Dillard's method are all included along with
marcum_1.0.0.tar.gz: Octave package for computing Marcum Q Functions
marcum_1.0.0.zip: Octave functions for computing Marcum Q Functions
A collection of octave routines for computing the
generalized Marcum Q function. The tar.gz file is in
octave package format for use with octave's pkg install
command. The zip file just contains the routines with
MSDOS-style line terminations.
UWB by Ghobad Heidari, Ph.D. with a chapter by Robert
T. Short, Ph.D., John Wiley 2008.
UWB (ultra-wideband) has been investigated for many decades
but only recently has it become commercially viable. With
the advent of WiMedia UWB technology and its associated
standard specifications, the stage is set for the next
generation of WPAN applications to take root.
WiMedia UWB focuses on the ECMA-368 standard. Both PHY
layer and MAC sublayers specified in this standard are
explained in great detail. The book offers not only the
facts about the requirements of the standard, but also the
motivation and logic behind them. To give a comprehensive
perspective of the UWB technology to the reader, other
interrelated topics are also examined in this book. These
include the history of UWB and its recent standardization
attempts; UWB applications and advantages; UWB spectrum
allocation and regulations around the world; UWB platform
clients: Certified Wireless USB (CW-USB), Bluetooth, and
WLP (WiMedia Link layer Protocol, which enables Internet
Protocol over UWB); as well as some important
implementation issues and considerations. As the first
application of WiMedia UWB, CW-USB is given a special and
more comprehensive treatment.
Fundamentals of OFDM by Robert T. Short, Ph.D.,
to be published 2013.
A thorough and complete introduction to the theory and
practice of OFDM and OFDMA systems.
