Brief summary
This book describes essential fundamentals of both analogue and digital transmission systems, in particular:
- Objective of modulation and demodulation: Frequency and time division multiplexing. Ideal, distortion-free and distorting system. Quality criteria.
- Amplitude modulation and associated demodulators: Double sideband– and single sideband modulation. Envelope and synchronous demodulation.
- Angle modulation and associated demodulators: Phase modulation and frequency modulation. Signal-to-noise ratio with angle modulation.
- Digital modulation techniques: Pulse code modulation, Linear modulation techniques $($ASK, BPSK, BPSK$)$, Non-linear modulation $($FSK, MSK, GMSK$)$.
- Multiple access methods: FDMA, TDMA, CDMA. Multiplexers and demultiplexers. CDMA spread sequences. PN modulation: Principle and realization.
Notes:
- The description builds on the books »Signal Representation« and »Linear and Time Invariant Systems«.
- Knowledge of »Theory of Stochastic Signals« is helpful, but not essential.
- Further details on digital signal transmission $($BER computation, system optimisation, ...$)$ are covered in the book »Digital Signal Transmission«.
⇒ Here first an »content overview« by means of the »five main chapters« with a total of »23 individual chapters« and »192 sections«.
