Error control coding should protect digital data against errors which occur during transmission over a noisy communication channel or during storage in an unreliable (=noise) memory. The last decade has been characterized not only by an exceptional increase in data transmission and storage requirements but also in a rapid development in microelectronics providing us with both a need for and the possibility to implement sophisticated algorithms for error control. Examples of today is CD, DVD, DAB, and DVB.
Introduction: Why error control? Possibilities! Terms of Error Control. Introduction of Block and Convolutional Codes.
Convolutional codes: Structures; equivalent, systematic, and catastrophic encoders. The Viterbi algorithm hard and soft decoding. Viterbi metric. Tail biting. Punctured codes. The BCJR algorithm.
Concatenated codes: Inner and outer code. Interleaving. Turbo codes. LDPC codes. Design of codes. Iterative decoding.
Block codes: Cyclic codes. Shortend codes. Discrete Fourier Transform. Shift register synthesis. Reed-Solomon codes; encoding and decoding. Minimum distance.
Grading scale: TH
Assessment: Written examination (5 h) normally consists of five problems. Approved project is a requirement to be allowed to enter the examination.
Required prior knowledge: For students from the E, D, C or Pi programmes: the compulsory courses. For students from the MWIR programme: ETT051 Digital Communications.
The number of participants is limited to: No
