CHANNEL-NETWORK CASCADE FOR PACKET AND SYMBOL ERASURES IN BINARY LINEAR NETWORK

Abstract

This paper covers the problems of packet and symbol erasures in binary linear networks. A method based on sequential cascading of network and channel codes to resist symbol erasures is described. The channel code is considered to be a code based on equal-weight columns. A non-linear subcode of rank code is used as a network code. Encoding and decoding algorithms for cascading code are constructed. A simulation model has been developed. With the help of this model experiments have been carried out to show the effectiveness of the presented method.
