Next Generation Communications
Abstract
(U) The Next Generation Communications program will develop detection and "reasoner" technology that will allow cognitive radios to recognize jamming attacks and then adapt to maintain communications in the presence of cognitive jammer attacks and dynamic interference of multiple cognitive network interactions. The program will develop models of adversary, commercial, and friendly cognitive radios and implement those models in a "reasoner" that assesses, in real time, the current and future dynamics of the communications network. Based on the predictions of the level of communication success vs. mission communication requirements, the "reasoner" within the cognitive radio will choose waveform selections/configurations that best achieve mission objectives. The "reasoner" will include the capability to analyze and select optimum waveform configurations during all aspects of a mission, to include initial alert, ingress, mission, and infiltration. The design effort will lead to new radio communication architectures, more robust radio communication networking and better understanding of selection amongst interference avoidance and interference suppression strategies based on the predicted outcome. (U) The Next Generation Communications will result in an original capability to predict communications performance in a complex electromagnetic environment that includes large numbers of emitters and various types of Red/Blue/White communication systems. These predictions will enable cognitive radios to select the optimum communications configuration for achieving success given the mission phase and objective. This program will also develop and construct a network of radios that implement interference alignment, solving practical design issues such as distributed synchronization.
