Consider the user-defined MATLAB function below,ht_mp_ch().
The function ht_mp_ch(), outputs the sampled version of the impulseresponse hmp(t) of the multipath fading channel as avector.
functionimpulse_response=ht_mp_ch(max_delay,L,decay_base,t_step)
t_vector=0:t_step:max_delay;
mp_tmp=0*(t_vector);
path_delays=[0 sort(rand(1,L-1)*max_delay)];
impulse_positions=floor(path_delays/t_step);
mp_tmp(impulse_positions+1)=exp(j*2*pi*rand(1,L));
mp_tmp=mp_tmp.*(decay_base.^(t_vector/max_delay));
impulse_response=mp_tmp/sqrt(sum(abs(mp_tmp).^2));
Explain what the variable on the left-hand side represents andjustify how the right-hand side expression is formulated by addingcomments to every line.
