I am in my 5th semester of computer science and we have a digital communication course. All the textbooks of digital comm. available in my library demand a prerequisite of Circuit analysis and Signals and systems. Is there any book which is self contained or at least less heavy on these background topics?

    $\begingroup$ Digital communications necessarily depends on signals. Without understanding of signal theory, you really stand no chance to understand what is happening in digital communication. There might be more-or-less self-contained books, but I don't think it'll be worth the hassle. Ask the professor what kind of signal theory book he'd recommend as basis for a CS student, and read that. $\endgroup$ – Marcus Müller Sep 6 '17 at 21:05

I highly recommend you the book Schaum's outlines of Analog and Digital Communications.

It will be the fastest refresher for the signal processing and probability concepts which are essential prerequisites for digital communications. It's not using that heavy math also, nevertheless, not a trivial one either ;-)

    $\begingroup$ I always recommend that book -- for the price you can get it used, it's a no brainer. $\endgroup$ – MBaz Sep 9 '17 at 15:06
  • $\begingroup$ Yes. Before any serious study of communications, the subjects in this book shall be mastered well. Then the more brainer ones can be tried :-) Definitely useful. $\endgroup$ – Fat32 Sep 9 '17 at 15:48
