  • 7 - Spectrum of Digitally Modulated Signals

  • Tolga M. Duman, Bilkent University, Ankara
  • Book:
    Fundamentals of Digital Communication Systems
    Print publication:
    23 January 2025, pp 290-317

  • Summary

    Digital transmission over bandlimited channels is studied. The concept of intersymbol interference (ISI) is described, and the Nyquist criterion for no ISI is derived. The raised cosine pulse, a widely used example of a practical communication pulse resulting in no ISI, is introduced. Both ideal and non-ideal bandlimited channels are considered. In addition, the power spectral density of digitally modulated signals is derived, and the spectral efficiencies of different digital modulation schemes are computed.
