11 Apr 2014 Multi Class SVM Model and classify training/test data sets into more than 2 classes with SVM. Author: Cody

It seems that the code considered each set of data individually, and not jointly. Do you have any reference for your algorithm? If so, I would be thankful if you share that.

For those who are working with MATLAB on a 64 bit operating system, please build a 64 mex function for the c code inside the zip folder.

The instruction is as follow:

1. mex -setup (choose the appropriate compiler)
2. mex greedyAlgSingleUser.c (building mex function)

08 Dec 2011 OFDM LSE Channel Estimation the performance of LSE channel estimation will be evaluated based on bit error rate in received data Author: Hamid Ramezani

Dear Aydar,

Thanks, and it is funny that you waited two years, I am really sorry for that. :) you know sometimes the life does not go as you expect.

Dear Aydar,

If we want to evaluate the performance of BER without any power limit on the transmitter, and we only consider the SNR on the data, (not pilots) then your right. Regarding your comment I recently submitted a project here, which will be published soon. There, we can see how the power allocation among pilots and data affects the total capacity of the network. I hope it would be helpful for the people who are interested in this field of study.

Hamid.

hello sir,
could you guide line me ,what should i do for ofdm channel estimation using filter bank and also dct instead of fft. i just starting my work but still not on right track.m also searching estimation using compressive sensing,m also download cvx tool but yet not working..
