Advanced In-Flight Interceptor Communications System (IFICS) Error Detection/Correction

Xenotran proposes to develop a forward error correction (FEC) device for use in Ballistic Missile Defense (BMD) systems for ensuring survivable and robust communications between the Battle Management, Command, Control, and Communications (BM/C3) elementsand an Exo-Atmospheric Kill Vehicle (EKV) during flight. Communications in this channel is known to be subject to Rayleigh and Ricean fading, intentional jamming and the communications deterring effects of nuclear detonations. Several new algorithmsbased upon iterative decoding have arisen in recent years that closely approach the Shannon limit for communications capacity and allow unparalleled FEC ability in these adverse channels. Yet, practical implementations of these algorithms are lacking. Xenotran anticipates that development of advanced FEC technologies for heavily faded environments will have large commercial applicability both in military space communications and in commercial Terrestrial 3G systems.
