The book, with a name of "The Channel and anti-interference Turbo code in satellite-to-ground optical communication links", is based on a set of lecture notes prepared for a first-year graduate course on the principle and technology of optical communication links, given in the University of Electronic Science and Technology of China (UESTC) for the past several years.

Lots of contents (especially refer to the theory and theoretic model) in this book are excerpted from the published references which were vended by the experts and scholars in domestic and overseas. This book labels the references cited as much as possible. However, because of restriction of different reasons, it is difficult to ensure that there is no omission and error, and hope learners of insight to criticize and make comment.
