Abstract :
A new equaliser for digital communication channels, which carries out a discrete-time fixed-lag smoothing of the state vector of the channel, modelled as a tapped delay line of finite length, is proposed. The smoothed estimate uses and improves the filtered estimate of the conventional Kalman-filter equaliser.
