OFDM with QPSK

OFDM Implementation using QPSK Modulation

Description

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.

OFDM with QPSK for R14

• Required Products: Communications Blockset; Simulink
• MATLAB release: MATLAB 7.4 (R2007a)

[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?

[xiaogang Yang]

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

I am a graduate student please help me in the programmes (OFDM,COFDM, Turbo- COFDM)

[Mounir ARIOUA]

Good job Muhammed!!, i need the file with ewtension .mdl, it's unable to download it !!

[zhongli wu]

Good

[AZHAR HADMI]

very good

[riad sayedahmad]

need the simulink for that program

[riad sayedahmad]

need

[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

[chaitanya jidge]

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

ada kode matlab mengenai OFDM pada kanal bernoise nggak??
kalo bisa saya minta yaaa..

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

[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

[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?

[RVCE S]

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?

[RVCE S]

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 [e-mail] ....

[m]

if u can email me the coding here is my email...
[e-mail]

[asd qwe]

hi can u send the .m and .mdl files please i need to refer, so it can help me understand where im going wrong

thanks

Hi,

Can you tell me the procedure to download the file ( .m) . I only have simulink and Matlab.

Thankx

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 [e-mail].

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

hi nadeem plz send me mfile at [e-mail]
