The lecture is not longer offered! Die Vorlesung wird nicht mehr angeboten!
Focus of the lecture is the procurement of fundamental knowledge for the description and calculation of the propagation of electromagnetic waves in mobile radio communications systems. Essential subject areas are the description of the propagation effects free space propagation, reflexion, scattering and diffraction, the characterisation of the system-theoretical properties of the radio propagation channel, wave propagation models, procedures for network planning, and fundamentals of multiple antenna systems (MIMO).
All course materials as well as a discussion forum can be accessed via KIT-ILIAS
Location: HSI lecture hall
allowed aids: One A4 page with own notes (that means ONE piece of paper and you can write on both sides of it), set square, non-programmable calculator
Registration: please use the link "Prüfungen" from above. If you can not register for this exam, the reason can be your student id. In this case, write an email with your name and id to tobias mahlerYxv6∂kit edu (but only in the case you can not register!). Registration up to one week before the exam.
