In this paper we study the MSE performance of a short ML channel estimator in a discontinuous block fading channel using superimposed pilots. The earlier analytical MSE estimates that we have seen were not concerned with ideal feedback or discontinuous block-wise transmission. In addition, we are interested in the scenario where we use shorter channel estimator than the true channel length. In this paper, we present solutions for these modeling problems and obtain improved analytic MSE estimates.
