Hi AHMAD SAUFUDIN,Â
It is my understanding that you want to modulate your data using DPSK.
- If you have your message data, feel free to use "dpskmod"Ã‚ inbulit matlab function.
- If you have access to PSK modulated data,Â use "pskdemod"Ã‚ for demodulating it first and use dpskmod to getÃ‚ dpsk modulated data.
- Else if you want to do it from scratch, look into the following code snippet
Further you can multiply carrier to y to get DPSK.
