Sunday Seminar:
A Stroll Through Software Radio, Information Theory, and Some
Applications
by Bob McGwier, N4HY
The S.day seminar this year will cover several technical topics.
Software Radio will be the main theme and a package of tutorials and
give away software will be a part of the seminar. The attendee will be
exposed to the basic concepts of and building blocks of a simple
software radio system and some information theory exposure will be
given. The quadrature sampling detector will be analyzed and why it is
such a wonder will be discussed. Its wonderful properties make it an
excellent choice for a linear transponder system so its use in the AMSAT
software defined transponder will be discussed. Some necessary
information theory will be discussed with examples with the goal of
leaving the attendee with a working knowledge of the practical use of
this theory in thinking about communication systems. Finally, as time
permits, we will show some software radio systems from the $30
softrock40 to GnuRadio/USRP doing multi megabit per second OFDM on the
air and then a technical description of the Flex5000 and DttSP will be
given.
