Digital Data Transmission by Baseband Pulse Amplitude Modulation
In this chapter you will be introduced to a common method for digital data transmission known as baseband pulse amplitude modulation (PAM). The presentation is slanted towards transmission over band limited channels and DSP implementation. The concepts learned here will be generalized to passband digital communication systems in Chapters 13–16. Some of the concepts and terms you will be introduced to are: baseband shaping filters and raised cosine shaping, intersymbol interference and the Nyquist criterion, eye diagrams, symbol error probability formulas, interpolation filter banks, and a symbol clock recovery method.
