Pulse Shape Optimization

4.1    Background

This chapter describes a method of pulse shaping or, more specifically, of generating low-complexity, spectrally efficient pulses for digital communications.

In digital communications, the data transmission is performed, in the most basic pulse amplitude modulation (PAM) scenario, by creating a train of identical pulses and multiplying each pulse by a number representing a symbol of an information-bearing sequence to be transmitted. The Shannon theory establishes a relationship between the data rate of a communication channel, the signal power, and the bandwidth. Specifically, both an increase in the power and the bandwidth yield an increase in the channel data rate. An ideal situation ...
