Abstract

Abstract: By using intrinsic feature of Logistic map that expands in forward iteration and contracts in inverse iteration at the chaotic region in combination with the minimal error rule, a non-coherent detection scheme for chaotic digital communications was proposed and realized. Simulation results of three Logistic-mapbased system indicate that the system performances are better even in low SNR condition and also this scheme is valid when there is little parameter mismatch.

Key words: communication, chaotic communication, non-coherent detection, inverse iteration method, bit error rate(BER)
