- Title
SIMPLE SYSTEM FOR TESTING SECURE VOICE COMMUNICATION IN WIRELESS NETWORKS.
- Authors

- Abstract
This paper presents the Matlab implementation of a low bit rate communication system for transmitting Mixed- Excitation Linear Predictive vocoder data, based on Matlab's ability to interact from Simulink with external programming languages (such as Java or C Dynamic Link Libraries). Even if the use of external functions in the Simulink Module has some limitations, it allows the rapid implementation of testbeads for secure voice communication between different computers (using the encryption operations provided by the Java Cryptography Architecture). The designed system was implemented and tested in a wireless communication system.
