If you really mean pi/4-QPSK and you know that pi/4-QPSK is [ pi/4,
3/4*pi, 5/4*pi, -pi/4] then what's the problem? You pretty much know
what it is your asking about.
If you're instead askin...Re: Changing x-axis of spectrum

Bevan Weiss - 2006-03-18 07:00:00
As Randy said, all I have heard concerning UWB is that it's an ultra
wide baseband signal.
I don't believe it requires any frequency hopping, as demodulation of
the signal should reduce the proce...Re: What's Es/No mean?

Instead of just giving you the answer, I'll step you through it
logically. Very simple of course.
If you were to transmit multiple bits, what would you call this multiple
bit transmission. ie...Re: Matched filter question
