Nonlinear Distortion in the DVB_C Receiver

Question asked by hcseu on Nov 8, 2006
Hello All:

Our research group is designing a receiver chip used in DVB_C
system, and I am interested in the distortion produced by the
receiver.
I read some papers about the nonlinear distortion prediction, and
a lot of them research the nonlinear distortion produced by the
transmiter or the power amplifier in the last stage of the
transmiter . It confused me that is it necessary to character the
receiver using ACPR,NPR,CCPR or just test the receiver using IIP3 or
cross modulation?
And I am also interested in the relationship between the nonlinear
distortion and the signal to noise ratio, can you recommend me some
solution?

Best Regards
