Professor Gu has taught the graduate level courses in systems engineering and design for many years and this book has evolved from course notes. As he has taught the course he has encountered students from the control area who want to pursue their study in wireless communications and students from the communication and signal processing areas who want to learn optimal estimation theory in order to solve their research problems.
From the reviews: In the monograph linear, discrete-time, finite-dimensional control systems with variable or constant coefficients are considered. ... The monograph contains also many numerical examples, which illustrate the theoretical considerations and results. The monograph is well written and well organized and presents many valuable and interesting new results concerning optimal control problems for linear discrete-time systems.
