Editor's Note: Popular File 2009

OFDM Signal generation and decoding using QPSK as the modulation technique. This type of OFDM is particularly useful for WiMAX and other Wireless and Multimedia Standards. QAM4 and QPSK is same modulation technique. Just run the Model and with different SNRs in the Channel Block observe the performance of the OFDM. Please leave your feedback for the model so that we can improve it.

Berhanu Eddo

I was trying to find channel frequency response of OFDM system by using pilot symbols and linear interpolation.I used matlab interp1() to interpolate. But the problem is I get NaN value for all subcarrier channels beyond the last pilot symbol. which is not correct.

What technic can I use to find estimation of those subcarriers that are out of range for interpolation?

Please suggest me some idea.
Thanks in advance!

Berhanu Eddo

Can any one send me the Matlab code through berhanu_2006@yahoo.com

It is very urgent.
Thanks in advance!

i have been working on viterbisim.m which is a built-in matlab example for understanding the ber tool.. i that i have tried to change the code rate to 2/3 with trellis structure of
t = poly2trellis([5 4],[23 35 0; 0 5 13]); but output ber graph is completely unexpected n highly fluctuated.. i m not working on simulink ..plz help me how can i resolve this issue ..
basically my project is on mimo-ofdm so far i have done ofdm transceiver which works ok without rayleigh which is like this
data source ->FEC(2/3)->qpsk->ofdm ......but i need to send bits in a loop for more accurate ber that is i dont have to guess in advance ! thats y i m working on viterbisim.m... plz help m i have hardly got 2months to submit it ...
thanks in advance

ella ella

oh very thanks buddy,if you can send me ofdm simulink for that,would be so gratefull and thanks in advance and my mail id is damu.reddy446@gmail.com.

Hi. Can you provide me the matlab file for the above simulation. I cannot download the file. I need the simulation for OFDM which i think is available with your code but i cannot find the format...like matlab(.m) format..Please help me out....If possible can you just mail the code to javier.gelabert@eng.ox.ac.uk

is this a matlab code or other?? i cant download thise file to .m format, any can u help me put in downloading and simulating it?

Tse Walter

great job! I am a graduate student with doing a WiMAX research, it's help me a lot.
but how can i change the SNRs in this program?

razwe hayath

plz let me have the literarure of this OFDM-CDMA and the related work sothat i can go ahead in my reaearch work, as i am a fresh research scholor

Thaer salahat

hi ... thnx alot but i dont know how to run it it gives me errors on the line 130 ... i think i have to define the functions bu m-file but when i download it it has just the simulation file only :s

can u explain the procedure to download and run the file.

Alaa M

I have run the program and it was helpful.
I want to plot:
1)BER v.s. No of users (capacity) of MC-CDMA and for OFDMA.
2)BER v.s. distance from BS d(m) of MC-CDMA and for OFDMA.
3)BER v.s. Eb/No (dB) of MC-CDMA and for OFDMA.
4)PDF v.s. CIR (dB) of MC-CDMA and for OFDMA.

Thanks

Yes, the file is not compatible in R14. Hope the improvement appear :)

Julian Groves

I would like to use these simulations...but I only have R14.
Is there any way for you to save these files in R14 format?
