Performance Examples

• MPEG movie of QPSK system with carrier frequency offset = 1/4 cycles/symbol and timing offset = 1/500 cycles/symbol.

• MPEG movie of QPSK system with carrier frequency offset = 1/6 cycles/symbol and timing offset = 0 cycles/symbol.

Real Data Set

Samples of the baseband I and Q output ports from the E4433B ESG-D are availabe for download in the matlab file (1.8 MBytes): IQtest_data.mat. The E4433B ESG-D was configured to as described above. The baseband I and Q output ports were sampled using the TMS320C6701 EVM evaluation board at a sample rate of 48 ksamples/sec.

Patrick and Brent of Team Juggernaut relax before the competition begins.	Meanwhile, Travis and Kevin of Team Juggernaut scramble to get their design up and running.
Scott and Brett of Team Big Black Box get ready for the competition. Note that Brett has his game face on...	Erik, Nathan, and John of Team SWRx try to hide their panic as the competition is about to begin.
The antennae are lined up and ready to go. Don't cross that line you cheater!	Team Made in Provo is aimed and ready to go!
A fine RF front end.	Another fine RF front end.
Another fine RF front end.	OK, we found the signal. Let the competition begin...
A fine looking constellation.	Another fine looking constellation. It kind of makes you feel warm and 'fuzzy,' doesn't it?
Decisions, decisions, ....	The 'eye' is still open...
The Big Black Box Design is purring like a kitten (well, a black cat...)	Pizza for everyone after the competition.
Julie, the Made in Provo MVP, relaxes as it slowly dawns on her that she now has time for sleep, food, and some upcomming temple ceremony...	Team Juggernaut chows down as Brent does his George W. Bush impersonation.
