End-to-End Communication System Using IIR Pulses

This example shows how to create an end-to-end communication system using OQPSK modulator and demodulator block using Butterworth pulses, custom pulse shape and an AWGN channel. This model also calculates the bit error rate between the transmitter and the receiver.

Use the Open model button to open the cm_ex_oqpskmoddemod_iir model.

In this communication system, to receive the IIR pulses the demodulator is in the Integrate and Dump mode. For this, set the Pulse Shape property to Custom and FilterNumerator to 1.
