1.5 Supplementary reading
An excellent text that treats much of the material here with more detailed coverage but less
depth is Proakis [21]. Another good general text is Wilson [34]. The classic work that introduced
the signal space point of view in digital communication is Wozencraft and Jacobs [35]. Good
undergraduate treatments are provided in [22], [12], and [23].
Readers who lack the necessary background in probability should consult [2] or [24]. More
advanced treatments of probability are given in [8] and [25]. Feller [5] still remains the classic
text on probability for the serious student.
Further material on Information theory can be found, for example, in [7] and [4]. The original
work by Shannon [27] is fascinating and surprisingly accessible.
The field of channel coding and decoding has become an important but specialized part of
most communication systems. We introduce coding and decoding in Chapter 8, but a separate
treatment is required to develop the subject in depth. At M.I.T., the text here is used for the
first of a two term sequence and the second term uses a polished set of notes by D. Forney
[6] available on the web. Alternatively, [15] is a good choice among many texts on coding and
decoding.
Wireless communication is probably the major research topic in current digital communication
work. Chapter 9 provides a substantial introduction to this topic, but a number of texts develop
wireless communcation in much greater depth. Tse and Viswanath [32] and Goldsmith [9] are
recommended and [33] is a good reference for spread spectrum techniques.
