Hi all, I am a student and quite new to dsp. I need some help with matlab. I am trying to write the matlab code that will sample the input data stream u = [+1 -1 +1 +1 -1] and make pusle shaping to nyquist raised cosine pulse before being transmitted to the channel. Is it that the PAM block performs the sampling function but only selects one pulse (middle pulse) to trigger the Tx Filter? The nyquist roll off factor with the function g(t) = (sin(pi*t/T)./(pi*t/T)).*(cos(alpha*pi*t/T)./(1-(2*alpha*t/T).^2)) must be used to get the pulse shaping done? How can i plot the input data stream to the continuous time signal after sampling and the corresponding output response of the filter? Anyone can help me and give me some idea? Thanks in advance. PMM
