There are many valuable and useful books on electrical
communication (References 1-5 are some examples), but they have
certain disadvantages for the beginner. The more advanced books
present some things in a basic way, but they are very narrow for an
introduction to communica tion. The introductory books are broader
but still narrow by our stan dards. Further, they often pick things
out of thin air rather than derive them. This book is aimed at
giving the beginner a basic understanding of a wide range of topics
which are essential in communication systems. These include
antennas and transmission, thermal noise and its consequences,
Fourier transforms, modulation and noise, sampling and pulse code
modulation, autocorrelation and power spectrum, optimum filtering,
gauss ian noise and errors in digital transmission, data
transmission, limits on data rate including information theory and
quantum limits, and source encoding. We have not included
communications traffic, switching, and multiplexing, nor protocols
for digital and computer communications. For these, Reference 6 is
excellent. In general, our book does not discuss the circuits used
for communication or the physics of radio propagation. We assume
that these will be taught in specialized courses, but such courses
are not prerequisites for this one. Chapter 1 introduces the
transmission formula or antenna equation and antenna directivity.
Only a very basic sophomore physics knowledge of electromagnetic
theory is assumed. The radar equation is also treated."
