The Wireless Communications course provides students with an insight into techniques for reliable communication via time- and/or frequency-selective radio channels. To this end, the physical and statistical modelling of the radio channel is first presented, which forms the basis for understanding the transmission methods adapted to these channel conditions. The most important transmission and reception principles are then presented, in particular the various diversity methods:

• Time diversity: maximum ratio combiner, error rate calculation for coherent and incoherent reception, interleaving
• Antenna diversity: SIMO, MISO and MIMO techniques
• Frequency diversity for frequency-selective channels: Single carrier method with sequence detection, band spreading method, multi-carrier transmission

Emphasis is placed on a clear derivation of the receiver principles as operations in a linear vector space. In addition, an insight into current cellular radio communication systems is given.

• Pulse amplitude modulation and orthogonal multi-plus modulation
• Optimal receiver
• Channel models for mobile radio
• Treatment of intersymbol interference
• Error rate on non-frequency selective Rayleigh channel
• Time, space and frequency diversity
• Channel coding
• Current cellular mobile radio systems
