Abstract :
A novel method to extract multiple input and multiple output (MIMO) chaotic signals using the blind extraction algorithm after transmitting in nonideal channel is proposed in this paper. In order to solve the multipath problem in the direct chaotic communication ultra wideband (UWB) system, a blind extraction algorithm based on higher-order statistic (HOS) technique to recover the primary chaotic signals is introduced. Simulation results show that the proposed approach has good performance in separating the primary chaotic signals even under nonideal multipath channel.
