During the lecture, the participants shall acquire basic knowledge of the functionality of cellular modems and their implementation in smartphones. The lecture is built from a systems engineering perspective and covers the full cellular system. The focus is on receiver algorithms, communication procedures, the interaction of the terminal with the network, and in addition some economic constraints that need to be considered during the development of a cellular modem platform. The lecture addresses these aspects applied to current cellular radio systems. After the lecture, students shall be able to transfer the learned systems approach to other applications.

Structure of the lecture: - introduction: cellular terminals as highly integrated systems - basics of cellular communications: network architecture, protocols - data transmission: radio channel, WCDMA and OFDMA, receiver structures - further topics: procedures, implementation aspects, productization - market environment, economic aspects - outlook on possible future developments in cellular communications

basics of signal processing, communication theory, communication networks

Classroom lecture. In addition to the individual methods of the students it is intended to create deeper knowledge by using descriptive case studies.
