Abstract:
The application of frequency-agile communications techniques, or Dynamic Spectrum Allocation (DSA), have proven to be effective for adaptive communication in many scenarios. In particular, DSA finds primary application in wireless systems, such as cognitive or software-defined radio. In this work, we implement a form of DSA which uses weighted statistical analysis of channel parameters and a heuristic decision process. This algorithm selects and prioritizes the most favorable subcarriers for multicarrier, frequency-division transmission while avoiding arbitrary spectral obstructions in occupied channels. We validate this technique in the context of "Smart Grid" communication, which provides a very useful means of exercising the capability of the algorithm.
