Dear Maimonah,

I'm afraid I just followed the 802.16d standard to implement the SUI channel features.

Maybe you can check the same files but English version.

Hope it helps.

Carlos

Hello Omprakash et al,

About bin_coef.dll error, please let me explain the reason I'm using it and you may workaround later:

You probably realize that it's empty, right? so let me explain you what the purpose for this file is, then you will able to delete it (or not):

To make the BER picture between my results and the theoretical ones, I need Matlab to know the latest one, right? I wanted to get those values from Matlab (berfading function) but my Matlab version (7 R14) didn't implement the option 16QAM and 64QAM in the berfading funtion.

Then, I asked for a solution to one of my colleague in Bremen and he gave me some routines : graytable.m, pb_psk_ray.m, pb_qam_ray.m, pb_pam_ray.m bin_coef-m y bin_coef.dll. I thought I could delete some files and keep those files I wanted, but it was not easy and I kept all the files into my folder.

You can delete all those files in case you rewrite the following sentence in the "BERteorica.m" file
"[Ps,v_ber_teoria]=pb_qam_ray (1:length(v_EbN0_dB),2^n_mod_tipo,1,'gray');"

....By the one that tells you the same data (depends on the Matlab version). I think it's like this:
v_ber_teoria = berfading(v_EbN0_dB,'qam',16,1);
(The issue was that I got an error using this command due to my Matlab version so I need the other files)

Hope you can now wave the bin_coef.dll use and perform the files properly.

Regards,
Carlos

Dear Sir,
what does bin_coef.dll do? i understand bin_coef.dll ? ???

Invalid MEX-file 'C:\Documents and Settings\Administrator\Desktop\802.16 System
-English version\bin_coef.dll': C:\Documents and
Settings\Administrator\Desktop\802.16 System -English version\bin_coef.dll is not a
valid Win32 application.
help me plz

do you have the code for generating the channel parameters for sui-3 channel?
