Optimal filtering

This book considers methods of optimal signal processing. The generalised filtering theory presented includes both highly developed, now classical branches like the Wiener-Kolmogorov and Kalman-Bucy theories, as well as relatively new branches such as semidegenerate processes and minimax filtering. The unique two-level approach to filtering problems is applied depending on their complexity. This volume will be of interest to experts in the design of signal processing and theorists in functional analysis, probability theory, and mathematical physics.
