227-0121-00L | Communication Systems | 6 credits | 4G | A. Wittneben | |
Abstract | Information Theory, Signal Space Analysis, Baseband Transmission, Passband Transmission, Example und Channel, Data Link Layer, MAC, Example Layer 2, Layer 3, Internet | ||||
Objective | Introduction into the fundamentals of digital communication systems. Selected examples on the application of the fundamental principles in existing and upcoming communication systems | ||||
Content | Covered are the lower three layer of the OSI reference model: the physical, the data link, and the network layer. The basic terms of information theory are introduced. After this, we focus on the methods for the point to point communication, which may be addressed elegantly and coherently in the signal space. Methods for error detection and correction as well as protocols for the retransmission of perturbed data will be covered. Also the medium access for systems with shared medium will be discussed. Finally, algorithms for routing and flow control will be treated. The application of the basic methods will be extensively explained using existing and future wireless and wired systems. | ||||

Abstract | The term wireless communications merges a large number of very different systems. This lecture allows a broad overview over current and future wireless communication systems and the implementation of fundamental principles of wireless communications. In parallel, market analyses shall help to measure the state of the art of these systems with respect to production, development and research. | ||||
Objective | Wireless access systems support locally constrained tetherless connectivity and mobile access to a backbone network (typically the Internet). A variety of fascinating new applications are enabled if we succeed in providing mobile wireless connectivity to heterogeneous nodes (including RFID enabled objects, sensors and actors as well as computers and other power devices). We refer to this breed of networks as pervasive wireless access networks. In this course the student develops a comprehensive understanding of pervasive wireless access technology, existing markets and upcoming business opportunities. | ||||
