1. A channel h is defined by its impulse response with h[0] = 0.5, h[1] = j/2, and h[2] = 0.4exp(jn/5). Use Matlab to calculate the Least Squares Equalizer of length Lf = 5. The LS Equalizer is given by fLS,na = (H*H)-H*ena squared error corresponding to a delay n_d is given by J[na] = e(I-H(H*H)-H*)ena a. Write down the channel convolution matrix H formed from the vector channel defined by h. b. Generate a plot of the squared error as a function of delay parameter. c. What is the delay corresponding to the minimum squared error min /[na]. d. Write down the fLs,nd using the delay value calculated in c.
