Hi,

 

when transmitting sine wave as baseband signal to modulator.  the constellation plot of  qpsk signal comes accurate as attached in sine_constelation.jpj file.

 

but when square wave is used as baseband signal and given to the modulator. the qpsk signal generated comes imbalanced as shown in fig square_constellation attached below.

 

Can any one help with this??

 

 

Thank You
