Content

The lecture "Advanced Channel Coding and Modulation" covers advanced methods of channel coding and modulation which are employed in modern digital communication systems, e.g., in the DVD- and Blu-ray-discs, in GSM-, UMTS- and UMTS-LTE mobile systems, in digital TV systems (DVB) or in WLAN internet access.

The lecture is held in English language. Prior knowledge of the basic concepts of digital communication is required, as is tought e.g. in the lecture "Kommunikationstechnik". Therefore, the basics of block coding, convolutional coding and digital modulation are just briefly summarized in the respective chapters.

The main focus are recent methods of channel coding for communication channels and storage devices with burst errors, as well as multi-carrier modulation which ist not only employed for DSL connections, but is an integral part of all recent communication systems for frequency selective channels.

In particular, covered topics are

  • Reed Solomon Codes
  • Turbo Codes (Block- and Convolutional Codes)
  • Low-Density Parity-Check Codes (LDPC)
  • Orthogonal Frequency Division Multiplex Modulation (OFDM).

In addition to the basic principles of these topics, the above mentioned applications are covered as examples.

In conjunctions with the lecture, exercises are offered. Additional lectures with coordinated topics are "Audio Signal Enhancement" and "Digital Speech Transmission".

The lecture notes have been developed to incorporate space for notes, examples and the derivation of proofs.
