Brief summary

This book describes essential fundamentals of both analogue and digital transmission systems,  in particular:

  1. Objective of modulation and demodulation:  Frequency and time division multiplexing.  Ideal,  distortion-free and distorting system.  Quality criteria.
  2. Amplitude modulation and associated demodulators:  Double sideband– and single sideband modulation.  Envelope and synchronous demodulation.
  3. Angle modulation and associated demodulators:  Phase modulation and frequency modulation.  Signal-to-noise ratio with angle modulation.
  4. Digital modulation techniques:  Pulse code modulation,  Linear modulation techniques  $($ASK,  BPSK,  BPSK$)$,  Non-linear modulation  $($FSK,  MSK,  GMSK$)$.
  5. Multiple access methods:  FDMA, TDMA, CDMA.  Multiplexers and demultiplexers.  CDMA spread sequences.  PN modulation:  Principle and realization.


Notes:

  • 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«.
