OQPSK Modulator-Demodulator Block Pair Use

This example shows the OQPSK Modulator Baseband and OQPSK Demodulator Baseband blocks connected with no channel or impairments distorting the signal between them. They are configured for frame-based processing with bit signal inputs.

Open the slex_oqpsk_mod_demod_pair model and run the simulation.

open_system('slex_oqpsk_mod_demod_pair');
sim('slex_oqpsk_mod_demod_pair');

The model displays the constellation of the OQPSK-modulated signal and computes the bit error rate of the recovered signal. The delay of the recovered signal, as determined by the Find Delay block, is applied in the Error Rate Calculation block. For perfect data recovery, the bit error rate is zero.
