Decoding of random network codes
Web(ME) decoders are required for random linear network coding. Despite the efforts toward reducing the complexity of ME or MAP decoders [10] [11], it is in general NP-hard to … WebEncoding and decoding. In a linear network coding problem, a group of nodes are involved in moving the data from source nodes to sink nodes. Each node generates new packets which are linear combinations of past received packets by multiplying them by coefficients chosen from a finite field, typically of size ().. More formally, each node, with …
