Abstract
The transfer of information over noisy and dispersive media has traditionally been, and still represents, an important subject of applied estimation and approximation theory. In this paper the specific problems encountered in synchronous data-transmission systems are reviewed. A first set of problems arises in timing-and carrier-phase tracking and in adaptive equalization, where continuous-valued parameters are to be estimated which may change slowly over time. A second set of problems deals with recovering the transmitted information from received noisy signals. It is shown that in the presence of severe signal distortion and/or redundant sequence coding the optimum receiver has to solve a dynamic programming problem.
