PPT-On error and erasure correction coding for networks and deadlines

Tracey Ho Caltech NTU November 2011 Network error correction problem 2 s2 z unknown erroneous links t 1 t 2 Problem of reliable communication under arbitrary errors on z. The bit stream representation of a symbol is called the codeword of that symbol Di64256erent error control mechanisms Linear Block Codes Repetition Codes Convolution Codes brPage 2br Linear Block Codes A code is linear if two codes are added using m FEC Basic Idea. Send redundant data . Receiver uses it to detect/correct errors. Reduces retransmissions/. NAKs. Useful when RTT is high. Types of FEC . Two types of FEC. Block codes (works on blocks/packets). Error Correction. Two ways of handling . error correction. The receiver can have the sender retransmit the entire data unit. The receiver can use an error-correcting code. To correct the error. Locate the invalid bit or bits. Real-Time Streaming. Derek Leong and . Tracey Ho. California Institute of Technology. Pasadena, California, USA. ISIT 2012. 2012-07-02. packet erasure link.
