Abstract :
In this paper we will investigate the performance of Raptor codes using Gallager´s majority decoding algorithm on the binary symmetric channels. We obtain equations which relate the error probability to the outputnode degree distribution and then we design good degree distributions using the differential evolution (DE) method
