Abstract:
1. A cognitive radio engine for controlling an adaptive radio, wherein the cognitive radio engine defines a radio chromosome, where each gene represents a radio parameter, said cognitive engine comprising: a wireless channel genetic algorithm (WCGA) receiving channel information from the adaptive radio and modeling the channel; a cognitive system monitor (CSM) receiving the modeled channel from the WCGA and determining if a new radio configuration is needed, building trends from the WCGA and radio statistics, and developing a set of fitness functions; and a wireless system genetic algorithm (WSGA) receiving the set of fitness functions from the CSM and developing a system chromosome and creating a fitness to match the fitness goal function, said WSGA passing a new system configuration to the adaptive radio which, in turn, reconfigures itself according to the new system configuration, said cognitive radio engine implementing a chaotic search with controllable boundaries to seek out and discover unique solutions.
