hi everybody!i need some help with this example!!could you please somebody help me!?


1. Simulation of digital modulations

Generate the vector of random bits (hint: you can use rand in MATLAB) . Map them according the constellation of QPSK, BPSK, 8PSK or 16QAM (selectable by the user). Filter the signals by raised cosine filter (hint: rcosflt, or rcosine+filter). Plot the vector diagram (hint: plot), eye diagram (hint: eyediagram) of filtered signal. Plot the filters output as a function of time. Create graphical user interface for setting the simulation parameters (hint: gui).
 

hi!

check matlab files on the net there are plenty.
just you have to know how to search
good luck
 

Re: hi!

yes i found many , but my professor told me that i dont have to creat the functions the modulations but i can use it str8 from matlab!thats my problem ,and the other problem is that im weak in matlab
 

hi!

there are files which use functions in the way you want you just need to filter the ones you have found. You may find part of what you want so you can work with them like puzzle.
you will not find a file that does 100% like you want.
After all you need to do something so that you will learn
