 28 Aug 2009 20:40 help needed for adaptive modulation based on FER |
|

Hello , i am doing a project on adaptive modulation based on frame error rate with convolutionaly coded data , and i need to have a relationship between SNT and constellation size M which will give the adaptivity .
i have come to a relationship but i dont know if its correct or not , my supervisor hasnt been here for more than a month and he doesnt reply to emails .
i need a code to find a graph between the spectral efficiency and SNR . and i desperately need help , as i will be submitting my report in two weeks time.
Any help / suggestions will be much appreciate.

Cheers and peace ,,
I asked for help about two weeks ago but nobody answered , however i came up with a few results myself , and i am proud of it ,
the results can be easily achieved on maple , if you consider the channel model described in Andrea's Goldsmith's book and adopt a frame based approach considering iid errors in every frame . the idea is to find the spectral efficiency using the results based on adaptive coded modulation but again with a frame based approach.
Yes i am glad that i did it myself and my supervisor is happy with me ,
But , i was expecting a lil bit of help here which was a bit disappointing, but it freaked me out and motivated me to study and search more about the topic .
thanks for that guys ,
but I am willing to help anyone who is working in this field.
Thanks and Regards ,
