ABSTRACT:
A system includes a supernode generator module configured to generate supernodes. Each of the supernodes includes a plurality of symbol nodes. A supernode splitting module is configured to split each of the supernodes into derived symbols. The total number of edges of the derived symbols in each of the supernodes is equal to a predetermined number of edges of each of the supernodes.
