QPSK simulations with upconversion.
Jul 18th, 2009, 3:57pm
Hi Everybody,

I'm experimenting some problems using simulink, I'm not understanding how to implement up/down conversion, how to set the frequency carrier of the QPSK signal, and over all, how to show the PSD in passband.

I'm using the freq. offset block (for simulate a Local Oscillator error), and everything is ok while `shifting my signal in the MHz domain. but when working in GHz I just can't see the signal.

please, if there is someone who can explain me where is my mistake I will appreciate. I'd also, learn how to work with workspace variables in simulink, how to declare them in simulink and how use them.

thank you in advance.
