Mobile Communications

This book discusses the main differences between fixed–line network systems and systems where transmitters and/or receivers are moving.  Many of the basics covered in previous books are still valid when you look at "Mobile Communications".

Please note:

• The description is mainly in the equivalent low-pass representation.
• Differences from previous books are due to the channel here, which is always a radio channel and mostly time-variant.
• Intersymbol interference is not caused by the frequency dependence of the medium  "electrical line"  or  "optical waveguide", but by multipath propagation due to reflections, resulting in constructive or destructive superpositions of the electromagnetic wave with its echoes.

Here first a  »content overview«  on the basis of the  »four main chapters«  with a total of  »16 individual chapters«:
