Abstract: Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a pre-detector that detects an estimated pattern in a digital input signal, and a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The circuit further includes a data dependent noise prediction filter that is adaptively tuned to detect a noise pattern, and that filters the noise estimate to provide a filtered noise estimate.

Abstract: Embodiments of the present invention include model-based controls to control photobioreactor operation and the growth of algae for use as a biofuels feedstock. In some embodiments, the model-based control can accounts for future conditions such as weather, product pricing, customer demands and/or other variables to operate the reactors in a manner that optimizes product revenues, minimizes costs or energy, maximizes photosynthetic or energy balance efficiency, and/or any combination of the aforementioned factors.

Abstract: Various embodiments of the present invention provide systems and methods for processing data. As one example, a circuit is disclosed that includes a digital input signal that is provided to a pre-detector that detects an estimated pattern in the digital input signal. In addition, the digital input signal is provided to a summation element that subtracts the estimated pattern from the digital input signal to yield a noise estimate. The noise estimate is provided to a data dependent noise prediction filter that is statically tuned to detect a highly correlated noise pattern, and provides a filtered noise estimate. In some cases, the circuit further includes a post-detector that performs a data detection process on the digital input signal reduced by the filtered noise estimate.
