N Chapter 5, we introduced the basic concepts involved in periodic signal generation.
Although we mentioned the idea, we intentionally deferred the discussion of aperiodic
digital communications signals until now. Since digital communications signals can be
generated using an unlimited number of different forms and specifications, we will only
introduce one of these forms and a few of the techniques that can be used to produce this
type of signal. Specifically, we will discuss
1. Random data and symbol generation.
2. Binary phase shift-keying (BPSK) using antipodal rectangularly shaped bits.
3. BPSK ...
