Chapter 11Communication Systems
This chapter explores the pivotal role of signals theory in the world of communication systems with a focus on the transmission and reception of information, particularly by radio. Various approaches to modulation and demodulation are presented from a signals theory perspective. Practical problems associated with the design and operation of radio receivers also find elegant solutions through the theory of signals and systems, which has been elaborated in earlier chapters. Digital communications examples span the range from Morse code transmissions to the pseudorandom sequences underpinning modern spread spectrum communications.
