- Inhalt
- Learning target: To acquire fundamental knowledge on the peculiarities of the physical layer of wireless communication systems with mobile users. Ability to design and assess transmission concepts for mobile communication systems.
Content: First, basic concepts of various mobile communication systems are introduced and classified according to different criteria. In the following, the basic principles of mobile communications are
discussed, which are valid for any wireless communication system. In particular, these are the mathematical description of time-variant mobile communications channels using stochastic processes, diversity principles in order to combat fast fading, multiplexing schemes, duplexing schemes, modulation (e.g. Gaussian minimum-shift keying, GMSK), and channel coding with special consideration of convolutional coding and decoding using the Viterbi algorithm as well as interleaving. Especially, the interaction of channel coding, interleaving and slow frequency hopping as applied in GSM as countermeasure against fast fading is analyzed. Receiver algorithms for channels with intersymbol interference are briefly addressed. The cellular concept of large systems like GSM and UMTS is introduced and methods for the analysis of wireless networks are covered in detail. For the example GSM, some further system aspects like handover, power control, slow frequency hopping and network topology are discussed.
