Abstract: Systems (200) and methods (100) for noise error amplitude reduction. The methods involve configuring a first microphone system (202) and a second microphone system (302) so that far field sound originating in a far field environment relative to the first and second microphone systems produces a difference in sound signal amplitude at the first and second microphone systems. The difference has a known range of values. The methods involve (128) dynamically identifying the far field sound based on the difference. The methods also involve (130, 132, 134) automatically reducing substantially to zero a gain applied to the far field sound responsive to the identifying step.

Abstract: A system and method for noise cancellation with noise ramp tracking in the presence of severe or ramping acoustic noise. The system conducts an estimation of the noise level in the input signal and modifies the signal based upon this noise estimate. A windowed Fourier transform is performed upon the input speech signal and an estimation of a histogram of the frequency magnitudes of the noise level and other related parameters is generated and used to compute a spectral gain function that is applied to components of the Fourier transform of the input speech signal. The enhanced components of the Fourier transform are processed by an inverse Fourier transform in order to reconstruct a noise reduced speech signal.

Abstract: A communications device includes pre-processing circuitry for processing a received wideband complex signal including an undesired narrowband interference component therein, and for determining a frequency of the undesired narrowband interference component. A filter is downstream from the pre-processing circuitry and operable to generate a received wideband complex signal with at least one frequency notch therein to suppress the undesired narrowband interference component. The filter includes a finite impulse response (FIR) filter with L taps to generate N output values, with L>N. A Fast Fourier Transform (FFT) block is downstream from the FIR filter and has a length N so that filter transition regions occur between frequency bins of the FFT block. A notching block is downstream from the FFT block to generate the frequency notch. An Inverse Fast Fourier Transform (IFFT) block is downstream from the notching block and has the length N.

Abstract: A circuit (100) is provided that is connectable between input lines (150, 152, 154) and output lines (160, 162). The circuit is comprised of a primary battery (103) and a hold-up battery (101). The hold-up battery is connected in parallel with the primary battery. The circuit is further comprised of an RC circuit (180) connected in parallel with the primary battery and is isolated from the hold-up battery by unidirectional current valves (108, 110). A comparator is provided with a first input (130) coupled to the RC circuit and a second input (132) coupled to a voltage reference. A switching device (104) is provided that is controlled by an output of the comparator. The switching device connects the hold-up battery to output lines in a first state and disconnects the hold-up battery from output lines in a second state. The unidirectional current valves prevent reverse leakage current from the hold-up battery from charging a capacitor during a discharge period of the RC circuit.
