====Fountain Codes==== /* template: ABSTRACT */ Talk intended for a general audience with networking background. The talk concluded with several demos, which are not available on the web at this point. This minicourse introduces the applications that have lead to the development of Raptor codes, and introduces the theory behind these codes. Emphasis is on codes designed for the binary erasure channel. An introduction into algorithms for decoding Raptor codes on the q-ary symmetric channel for large q. The talk discusses capacity-achieving sequences for the erasure channel and for the q-ary symmetric channel for large q The talk discusses capacity-achieving sequences foThe talk discusses threshold phenomena arising in the study of fountain codes on various channels. Introduction to Raptor codes on binary input memoryless symmetric channels. Introduction to Fountain Codes on the BEC and binary input memoryless symmetric channels. Codes auf bipartiten Graphen
