TSKS13 Wireless Communications

This course gives basic knowledge about problems and solution methods for construction of wireless communication links and systems. The emphasis is on digital wireless links and the course sheds light on, among other things, how different types of signal processing can be used for construction of effective wireless systems.

TSKS13

Course topics

  • Basics about radio communication systems: utilisation of the frequency spectrum, varioust radio systems.

  • System oriented antenna and wave propagation theory: propagation in free space, in the troposphere, in the ionosphere, basic antenna theory, link budget.

  • Probabilistic channel models: fading channels, time and frequency dispersive channels, digital channel models.

  • Modulation methods for the radio channel: bit-error-rate analysis in fading channels, spectral properties, spectral efficient modulation, OFDM.

  • Diversity methods: principles, weighting, performance.

  • Coding for radio channels: methods for burst error correction, coding gain.

  • Spread spectrum techniques: frequency hopping, direct sequence systems.

  • Wireless packet transmission: ARQ, multiple access techniques - ALOHA and CSMA.

  • Wireless cellular systems: basic concepts, frequency reuse capacity calculations.

  • Practical examples: GSM, WLAN.
