1. consider the following joint pdf 0 otherwise.
(a) determine the mmse estimator mmse(y) of x given y-y
(b) determine the mse of the mmse estimator e[(x - fmmse(y)].
(c) determine the llse estimator llse(y) of x given y-y
(d) determine the mse of the llse estimator e[(x-rllse(y))2].
2. consider the following joint pdf 4 -x > 0, y 0 otherwise. 0, x2 + y's 1 fx, y(x, y)
(a) determine the mmse estimator mmse() of x given y-y.
(b) determine the mse of the mmse estimator ei(x mmse(y))
(c) determine the llse estimator tllse(y) of x given y-y.
(d) determine the mse of the llse estimator e(x ll(y)
