Collaborative Interference Cancellation for Group Communications

To meet the critical need for military wireless communications to take place over large distances in the presence of interference, we propose to develop a collaborative group navigation and communication (COGNAC) system that will enable mobile platforms to collaboratively null interference in order to communicate from one collaboration group to another in anti-access/area denial (A2/AD) environments. To this end, we adopt a tight integration of position, navigation and time (PNT) with networking and communication approach. Four technical innovations are anticipated, namely, (i) intra-group networking (IGN), (ii) collaborative group navigation (CGN), (iii) collaborative interference cancellation (CIC), and (iv) group communication optimization (GCO). In Phase I, we will perform algorithm design for the proposed COGNAC system and evaluate its functionality and performance using computer simulation with realistic measurement models and scenarios. In Phase II, the algorithms designed in Phase I will be implemented into a prototype system for demo and evaluation. Further development will be made for target customers to enable military and/or civilian applications in Phase III.
