Abstract :
Results regarding two aspects of joint maximum likelihood (ML) data sequence and intersymbol interference channel estimation are considered: (i) the joint-ML estimation problem is ill-posed when based on the continuous time observation, and (ii) processing based on a discrete time signal model yields equivalence classes of data sequences
