Brief summary

The focus of this book is the  »calculation of the error probability«,  which is the decisive quality feature for digital systems.  The description is mainly in baseband,  but most of the results can also be applied to the digital carrier frequency systems.

  1. Error probability and optimization of baseband transmission systems.  Properties of Nyquist systems.  First and second Nyquist criteria.
  2. Fundamentals of line coding:  Redundancy-free codes,  blockwise  $($4B3T$)$  and  symbolwise encoding  $($pseudoternary codes$)$.  Power spectral density.
  3. Optimization considering intersymbol interference:  Eye diagram,  linear Nyquist equalization,  decision feedback equalization,  Viterbi receiver.
  4. Generalized description of digital modulation schemes:  Basis functions and vector spaces,  coherent and incoherent demodulation.
  5. Digital channel models:  Error distance distribution and error correlation function.  BSC model.  Gilbert/Elliott and McCullough bundle error models.


Notes:


⇒   Here first an  »overview of contents«  on the basis of the  »five main chapters«  with a total of  »26 individual chapters«  and  »201 sections'«.
