Claim 4:
5. A Neuromorphic Adaptive Core (NeurACore) cognitive signal processor (CSP) for wide instantaneous bandwidth denoising of noisy signals, comprising:
a NeurACore block, the NeurACore block being operable for receiving as an input a mixture of in-phase and quadrature (I/Q) signals and mapping the I/Q signals onto a neural network to determine complex-valued output weights of neural states of the neural network;
a global learning layer, the global learning layer operable for adapting the complex-valued output weights to predict a most likely next value of the input I/Q signal;
a neural combiner, the neural combiner operable for combining a set of delayed neural state vectors with the weights of the global learning layer to compute an output signal, the output signal being separate in-phase and quadrature signals; and
wherein the NeurACore block is configured to handle both real and complex-valued I/Q signals, with the CSP operable with matrices A and B as follows:, [
