Communication system with chaotic carrier on the digital signal processor ADSP-2181
Autors:

Abstract:
The realization of a communication system with a chaotic signal as carrier using digital signal processors is considered. The conditions of chaotic synchronization stability for reception and transmitting subsystems for two investigated architecture using the digital chaos generators with sawtooth nonlinearity are obtained. The influence of distortions in the transmission channel to communication qualify is analysed. Some issues of experiments on speech signals fransmission with chaotic modulation through the analog channel are shown.
