I am having a weird problem with a passband QPSK simulation I am
working on. I just need the modulated output for further pprocessing
and dont want the demodulation in my simulation. When I just use the
M-PSK modulator the transmitted output is like a square wave. When
there is a M-PSK demodulator in my simulation then the modulated
output(from M-PSK modulator) observed in my scope looks as it
should.Is this a bug in simulink? Did anyone come across this before?
