J-DSP Blackboard for Collaborative Simulations

Description: This is a new J-DSP version that supports collaborative simulations and J-DSP chat features. Two users can work on the same J-DSP Environment. A J-DSP chat facility provides communication capabilities between the two users. The infrastructure developed is based on Java Sockets and J-DSP Scripts. J-DSP Blackboard concept by Prof. Andreas Spanias.

Please read the J-DSP manual for operating instructions and to get started with collaborative simulations.
