Consider the wireless channel model given as y(n) = hx(n) + w(n). Show that the least square channel estimate ĥ, represented as h= = arg min ||y(P) - hx(p)||² h has an optimal solution given by h (x(p)) Hy(p) = where x(p), y(p) are the vectors of length ||x(p)||2 L corresponding to the transmitted and the received pilot symbols. Here (.) corresponds to the hermitian operator.
