Abstract:
1. An adaptive, intelligent, transform-based, analog to information converter system comprising: an analog transform converter module for receiving an analog signal including information and for decomposing the analog signal into a plurality of sub bands; and a feature extraction and classification module coupled with the analog transform converter module for receiving the sub bands from the analog transform converter module and for performing a classification operation for determining analog signal portions corresponding to at least one transmitted analog signal portion and an interference analog signal portion, and increasing the feature-to-noise ratio of the analog signal to maximize the fidelity of the transmitted analog signal portion to generate an improved-fidelity representation of the analog signal; a sampling module coupled with the analog transform converter module and the feature extraction and classification module to receive the sub bands from the analog transform converter module and to sample each of the plurality of sub bands to produce sampled sub bands, where at least one of the plurality of sub bands is sampled using a sampling rate different from a sampling rate used to sample another of the plurality of sub bands, and to provide the sampled sub bands to the feature extraction and classification module; with the feature extraction and classification module further comprises a combinatorial selection module for receiving the sampled sub bands and combining sets of sampled sub bands to generate different transform optimally for a given signal.
