21 May 2012 MPSK Simulation (BPSK,QPSK,8PSK) This m-file simulates MPSK (theoretical and simulated) with Gray coding Author: J C xu

i have the same problem with holly :
??? Error: File: graymapPSK.m Line: 8 Column: 17
The expression to the left of the equals sign is not a valid target for an assignment.
Error in ==> MPSK at 49
symbols = graymapPSK(bits); % gray code map to symbols

i want the graymapPSK function

thank you for this coding

29 Oct 2011 UWB Analysis Plots time and frequency domains of UWB PPM monocycles and doublets with basic correlation receiver. Author: J C CIPRIA

Thanks for this simple UWB pulses demonstration with pulse position modulation (PPM).

I use your doublets (second derivative Gaussian pulse) with and without pulses train and then we can see periodic variations on frequencies display - fine.

The very simple correlation separate correctly single pulses from delay pulses like PPM must do !

I was excited about the result and delighted by the simplicity.

You write the equations completely so that we can change at will by mastering what we do well.

Congratulations and thank you.
