Abstract

We look at the well studied problems of sequence estimation in unknown or fading channels, and introduce yet another set of algorithms that have reasonable complexity and perform well even in fast changing environments. The algorithms work on a block-by-block basis and utilize periodically, but sparsely inserted known data symbols. In producing their channel estimates, however, the algorithms do make use of the information contained in the received modulated data, thus reducing the rate at which known symbols need to be inserted, and improving performance. Simulation results show good performance for the algorithms.
