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.
- Error probability and optimization of baseband transmission systems. Properties of Nyquist systems. First and second Nyquist criteria.
- Fundamentals of line coding: Redundancy-free codes, blockwise $($4B3T$)$ and symbolwise encoding $($pseudoternary codes$)$. Power spectral density.
- Optimization considering intersymbol interference: Eye diagram, linear Nyquist equalization, decision feedback equalization, Viterbi receiver.
- Generalized description of digital modulation schemes: Basis functions and vector spaces, coherent and incoherent demodulation.
- Digital channel models: Error distance distribution and error correlation function. BSC model. Gilbert/Elliott and McCullough bundle error models.
Notes:
- A basic knowledge of "Signal Representation" and "Stochastic Signal Theory" $($Books 1 and 3$)$ is assumed for understanding this book.
- There are certain, quite intentional overlaps with the book "Modulation Methods".
- Mostly a time-variant channel is assumed. Time invariance is dealt with in the books "Mobile Communications" and "Examples of Communication Systems" .
⇒ Here first an »overview of contents« on the basis of the »five main chapters« with a total of »26 individual chapters« and »201 sections'«.
