As a text book however I feel that it is perhaps too ambitious for a person new to the topic. I would have preferred lucidity of explanations over the depth of coverage for a text book of a course. My favourite book for this is still Woodrow and Wilson's classic text even though it is quite old and does not cover most new developments in the field.

However as a reference for those already somewhat aware of the topics, or for the serious DSP researcher, this book is an excellent resource which gives a very good review of most of the published material in the area.
