communication system time series

1. The problem statement, all variables and given/known data







d1 = [1 0 0 0 0 0 0 0 0 0 0 0]

d2 = [0 1 ....0]

and so forth to d10



3. The attempt at a solution

(a)

The optimal delay is 7 in part.

b) Is optimal equalizer coefficients the estimated Dhat associated with the delay 7 (i.e. Dhat=A(A'A)^-1A'd7 )?

c)

channel frequency response is H_c (f) = .4+.7exp(-j*2*pi*f) -.1exp(-j*2*pi*2*f)

What is the equalizer frequency response? Would it be the coefficients for dhat and put put into the similar form as the channel frequency response?
