Abstract:

An implementation based on Chaos Theory is proposed to solve the problem of recovering the degree and the neighbor relations in encoding packets of fountain codes. Considering the composite Logistic map and its phase space character and using the initial values of the chaotic formula as public keys, the proposed implementation can synchronize the degree and the neighbor relations without extra packet costs. Simulation is done to verify the conclusion.

Key words: fountain codes, luby transform codes, chaos, logistic map
