Trying to modulate an MP4 file using QPSK modulation for transmission using an external antenna

I am a Master Degree University Student currently working on a project to demonstrate QPSK modulation, and I am trying to take a video file (anything doesn't have to be MP4) do some signal processing and then modulate the signal using QPSK.

I have already design and am currently building the antenna to transmit the signal, but software is really not one of my strenghts and I am struggling with using MATLAB for my purpose.

I was playing around using Simulink blocks, so far I've tried using the From Multimedia File block to read a MP4 file and display it as a video, but when I try to connect it to a QPSK Modulator Baseband block an error comes up saying QPSK block doesn't take signals with more than 2 dimensions.

Honestly I have no idea why I was set this project as I chose the topics on Network Management.

Any help or suggestions is most welcomed and thanks for your time,

Sharp

Did you get this working ?
