Hello everyone, 
  
   My name is Carlos and I've done this routine because I'm helping a friend with a work about OFDMA.
    
   He told me if I could help and I absolutely answered 'YES', but there is a problem...I haven't got
     enough time for the support, so I did this light version that it works at first but you cannot
     do everything you want because I know it has a few errors.

   Despite that, you can use it in a first aproximation and modify it if you want and need it.

   About my other file on Mathworks : "A 802.16d System". Many people tell me if I have an English
    version. I haven't this version but I'm trying to translate into English, in fact I've already 
    translated part of this, but I haven't enough time neither. (It's summer!!! I need a rest!!!)
    I'll finish it as soon as I could.

   Thanks for your patient.

   Best Regards, 

        Carlos


(p.s.- Sorry about my English.)
