Livingstone's Review
A practical book written in a good style to be found useful by both beginners and advanced users. The concepts of practical DSP with focus on applications to communications are well explained.

Some of the algorithms, like in DSP based Modems, would be found immensely useful to both academic and practicing engineers.
