Transsmiter image through QPSK modulate

Hello,

I need to change an image into a byte array and then transmit it through QPSK modulate.

Someone can help me how can I build a QPSK modulate?

I have changed the image to byte array by using de2bi on the image and then vec2mat.

What do you think about it?

Hi shmuel manashirov,

To do QPSK modulation on any data, first you need to create an object to QPSK modulator. You can create it using comm.OQPSKModulator . Refer this documentation to know more about it. Next you should call this object as if it were a function.

Refer to this example for better understanding.
