OP, is this your book? If so, can you talk about it? I never came across the first ed. It looks extremely practical compared to a typical comms book. I suspect that's due to the author coming from an extensive industry background.
Not the author, but it's really a good book. I've the first edition, planning to buy the new 2nd edition.
Do you know what's new in the 2nd edition?
The 2nd edition has 200+ increased in pages count compared to the 1st edition. Chapter's structure is about the same but there's one new additional chapter on transmitter design. In addition to that there's an extension to review of linear algebra (now two parts instead of one). I have not yet received my 2nd edition but from the ToC it seems that the new book will be an excellent textbook to learn DSP for communication systems.
