Course is intended as an introduction to mobile communication sysyems and consists of 3 modules: Fundamentals of communication, Transmitters and Radio receivers..
Fundamentals of communication is the first module. It covers the basic structure and implementation of data communication systems, communication channel, as well as mobile wireless communication network structure and operation principles. Examples are presented from digital communication systems, their elements and mobile communication systems 2G, 3G, 4G. .
In this mudule there are presented digital signals, modulation and errors in channel, Shannon’s theorem, throughput of Gaussian channel, as well as signal coding with block codes and convolution codes. .
There are given the examples of processing and transmission of signals in wireless mobile cellular networks, available frequency bands and signals, interference and noise, modulation schemas (FDMA, TDMA, CDMA), their specifications, as well as.
antennas used in mobile communication systems and radio wave propagation models in mobile communication. .
The second module is Transmitters. There are covered Radio frequency (RF) oscillators, efficiency of transmitter, power combining. As an examples are presented transmitters used in the Base Stations and safety engineering in application of transmitters. .
The third module is about Radio Receivers. It covers topics about methods and circuits used in radio signal reception: input circuits, selective RF amplifiers, frequency converters, detectors and automatic controls used in radio receivers. There are also presented examples of receiver concepts used in mobile communication systems – direct conversion, software defined and cognitive radios. .
