Frequency Selective Channel Coefficients in MATLAB
9 views (last 30 days)
How can I generate the following channel coefficients in MATLAB, where these coefficients correspond to a frequency selective channel:
f_m=sum_p h_p exp(-j*2*pi*fc*tau_p) g(mTs-tau_p), m=0,1,...,L-1
where g(t) is rectangular pulse of support duration Ts, and h_p, tau_p and fc are given.
Thanks in advance

here is a start :
fc=300; % Hz
d=4; % four signals per example,
tau is dependent on physical parameters, distance and coordinates, but i consider here a linear progressive phase, and the signals are sinusoidal :
your assignment now is to replace the sin signals with the rectangular ones .
