摘要：

In this paper we investigate the digital speech communication by active-passive-decomposition (APD) synchronization in a hyperchaotic system with a one-way coupled ring map lattice with length in. We present an analysis of the synchronous principle, synchronization time, and the sensitivity of synchronization to the parameter differences. Experiments as well as theory demonstrate that the APD method leads to secure encoding, short time synchronization, and recovery without error.
