Question

Calculate cochannel interference ratio using matlab

Answer 1

The communication system in this example includes these components:

A transmitter, which creates a PSK modulated signal and applies a square root raised cosine filter. The result is the original signal to which interference is added.

Two interferers, Interferer1 and Interferer2, each of which is similar to the transmitted signal but has a modifiable frequency offset and power gain. A sum block in the model adds the two interfering signals to the original signal. By default, both interferers are active; however, you can deactivate one or both interferers, as described in Experimenting with the Example below.

An AWGN channel.

A receiver, which filters, downsamples, and demodulates the received signal.
