Adjacent Channel sweep BER simulation
As the simulation is running you will see in the "Spectrum" graph the interfering QPSK signal's center frequency (QPSK2) sweep from 8.5GHz to 11GHz. You can monitor the impact of this on the BER performance of the 10GHz QPSK signal in the "BER" graph.
The SNR of the desired 10GHz QPSK signal is held at a constant value of 8dB during the frequency sweep.
The system diagram "QPSK BER" and graph "QPSK BER vs SNR" are for reference.
