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..
can someone explain this:
G = (Ep * length(Ip))^-1 ...
Why it is not just the inverse filter from Ypilot and Spilot? Like hHat = Ypilot/Spilot ?
