Abstract: Described is a cognitive signal processor that is implemented in a field programmable gate array (FPGA). During operation, the FGPA receives a continuous noisy signal. The continuous noisy signal is a time-series of data points from a mixture signal of waveforms having both noise and a desired waveform signal. The continuous noisy signal is linearly mapped to reservoir states of a dynamical reservoir. A high-dimensional state-space representation of the continuous noisy signal is generated by digitally combining the continuous noisy signal with the reservoir states. Notably, the continuous noisy signal is approximated over a time interval based on a linear basis function. One or more delay-embedded state signals are then generated based on the reservoir states. The continuous noisy signal is then denoised by removing the noise from the desired waveform signal, resulting in a denoised waveform signal.

Abstract: A method for providing pink noise and improving computational efficiency including providing NS stochastic signal generators, generating a respective first random number g with variance ? and generating a respective second random number u for each respective stochastic signal generator at each discrete time n, comparing the respective second random number u with an update probability for the respective stochastic signal generator at each discrete time n, if the respective u is greater than the update probability, then not changing a respective output of the respective stochastic signal generator, if the respective u is less than or equal to the update probability, then updating the respective output of the respective stochastic signal generator to be equal to the first random number, and summing at each discrete time n the respective output of each of the NS stochastic signal generators.

Abstract: Disclosed is a hardware scalable channelizer (“HSC”). The HSC includes an integrated circuit (“IC”) that utilizes neuromorphic processing. The IC also includes an IC input configured to receive an input signal and a plurality of infinite impulse response (“IIR”) channelizer filters in signal communication with the IC input, where each IIR channelizer filter of the plurality of IIR channelizer filters is configured to select a frequency band from the input signal and provide synchronous filtering of the input signal.
