Yes. 1. Start MATLAB. 2. Start coding. Or were you looking for somebody to give you the complete code for free?

For your information i have implemented OFDM in matlab using QPSK....i have also implemented OFDM using MFSK but just confused about its implementation ......and i am not wanting a code for free ....its was just an idea on how to implement ..........people here help each other for free ......if you help people for money than you should better leave this group .....i guess this is not the right place for you ....(by the way you should know that there are many codes available on the internet for free)

This seems implausible. If someone has implemented something, and has hit a problem, I would expect a much more focused question than the one you posted. Your question screams of "I'm too lazy/stupid to do anything. Please do it for me". Steve

From what I've read, OFDM-MFSK only uses sends one subcarrier per block of M in any given symbol. I can see an advantage to this because the subcarrier phases can be arbitrary, allowing PAPR to be optimized, but I'm wondering what other advantage there might be that outweighs the 1/M reduction in throughput.

you cant say this thing about anybody if u dont know him right it may be
that i lack any writing skills and i dont explain my questions rightly

hi 
   i want to confirm that if i use 4-FSK for data 00 10 01 11
can i use the the following data [1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1]
is it right to send data like this i have choosen a 0 phase for every
subcarrier in this case
thanx for your kind reply
