i need to know how to stimulate MPSK signal in OFDM using MATLAB
 

I don't see were you are facing problem?
simply generate your MPSK signal using randsrc then use ifft(.) for this signal to generate OFDM signal and then add CP to the begining of OFDM signal
 
hi farzad_m

why to use randsrc command we can use randint and modulate the signal using the modem object.

if i am not right please explain for me as i am dowing my ofdm simulation system now.
 

i have link already by what is problem is that it must stimulate MPSK signal in OFDM through linear constellation precoding technique. please help me.

Added after 3 minutes:

how linear constellation precoding works in OFDM in order to reduce PAPR
 

hi aya
how to do implement cp before ofdm signal

ohh, how you put the cp before the ofdm symbol? this is wrong.

after successful generation of the ofdm symbol, you have to put the cp
