ABSTRACT:
A technique for modifying communication operational parameters using fast, low complexity, accurately calculated SNR values. Techniques may improve upon prior art by calculating SNR values in a more color noise insensitive manner in the frequency domain. An agent may be implemented to calculate SNR values and either store or use the SNR values to modify operational parameters in communicative system.
