About length of the signal In my research work i have the equation y(n) = hx(n)+w(n). My understanding about this equation from MATLAB point of view are:


h has to be a single number. (for e.g., rayleigh generated).
x(n) , w(n) will be vector because they have n associated with them. So is my understanding correct or is their any other concept. Thanks.
I beleive that h can be a vector or scalar .. depends on channel taps i.e. h

y[n] = hx[n] + w[n]  -- indicates  h convolved with x[n]  and then added to noise w[n]
