Simulating Adjacent Channel Interference - URGENT

Hello...

I have a QPSK system with a interference by adjacent channel.

In my simulation, the four interfering channels is at 20 dB below the white noise considering my signal band.

Despite of this big difference, when I add the four interfering signals the system suffers a degration about 1.1 dB.

Why is it occurs??

The interference is very small in my system band.

I will send my system in attachment.

Thanks a lot!

I am waiting a answer...

With the best regards

Luciano
