Hi friends,
I'm trying to decode the QAM receiver part. Here I have obtained a cosine shifted waveform which I need to convert it to square wave(to get Q-channel) to get the data. I have attached a jpg image file. please take a look at the image because you may get many ideas to decode data. The red line marked is what I need to extract, now what are the ways to get the square wave/data(red line) from this waveform as shown in the pattern. The values in the left side are exact. Any ideas like comparator or some other coding techniques if provided will be much appreciated. I can't use filter techniques. So please it'd be great if you could provide me some other tips or ideas. thank you in advance.
Note:- This is Matlab-simulink based system generator model for QAM. I can either use m-file or xilinx blocks for doing these operations. VHDL or Vlog is optional.
