Digital Communications Conference
September 28-30
The 26th Annual ARRL/TAPR Digital Communications Conference
to be held on September 28-30, 2007 in Hartford, CT will feature topics
of interest to amateur satellite operators.
AMSAT Director and VP Engineering, Bob McGwier, N4HY,
will have several presentations.
On September 30 Bob will present the Sunday Seminar,
'A Stroll Through Software Radio, Information Theory, and
Some Applications.' Software Radio will be the main
theme and a package of tutorials and give away software will be a part
of the seminar.
The Software Defined Radio linear transponder system in AMSAT's spacecraft
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.
As time permits, Bob 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.
Additional Software Defined Radio topics among the digital offerings
at the conference include:
• The FSM Virtual Radio Kernel: Why, What, & How (In That Order);
Frank Brickle, PhD, AB2KT
• AMSAT¹s Phase IV (lite)?; Bob McGwier
• On A Method for Automatic Image Balancing in IQ Mixer Based Software
Defined Receivers; Bob McGwier, N4HY
• TPSK31: Getting the Trellis Coded Modulation Advantage;
Bob McGwier, N4HY
• The Flex 5000 Software Defined Transceiver;
Gerald Youngblood, K5SDR
And also known to AMSAT members, Bob Bruninga, WB4APR
has written a paper for the conference: The APRS Local Voice Repeater
Initiative.
