Hello all,

I attached a file that contains the math of transmitting single carrier (SC) modulated signal over frequency selective channels. I need to implement this in MATLAB as it is in continuous time. In particular, I need to generate the baseband received signal as in eq. (1.3), the received samples as the second line in eq. (1.5), and the channel coefficients as in eq. (1.6a). I use the following parameters:

N=128; %Number of symbols
fc=12*10^3; %Carrier frequency
B=1000; % Bandwidth
Ts=1/(2*B);%Nyquist Sample Time
nsamp=10^3;%Oversampling factor
Ta=Ts/nsamp;%Sample time after oversampling
K=N*nsamp;%Number of symbols in sample time Ta
tau=[0 5 7 20].*10^-3;%Pathe delays
h=[1 0.8 0.7 0.5];%Fixed channel coefficients.
