Abstract
Systems, methods, and apparatus for denoising signals are disclosed. In one aspect, an apparatus is provided. The apparatus may comprise a first denoiser configured to receive an input signal and to generate a denoised signal and a signal reverser configured to receive the input signal and to generate a time reversed signal. The apparatus may also include a second denoiser configured to receive the time reversed signal and to generate a denoised time reversed signal. Further, the apparatus may include a signal combiner configured to combine the denoised signal with the denoised time reversed signal to generate an output signal.
Claims20
An apparatus comprising:
- a first denoiser configured to receive an input signal and to generate a denoised signal, wherein the denoised signal includes near-zero phase error and near-zero phase delay;
- a signal reverser configured to receive the input signal and to generate a time reversed signal;
- a second denoiser configured to receive the time reversed signal and to generate a denoised time reversed signal, wherein the denoised time reversed signal includes near-zero phase error and near-zero phase delay;
- and
- a signal combiner configured to add the denoised signal and the denoised time reversed signal to generate an output signal.
A method comprising:
- denoising, at one or more denoisers, an input signal to generate a denoised signal, wherein the denoised signal includes near-zero phase error and near-zero phase delay;
- performing a time-reversal operation on the input signal to generate a time reversed signal of the input signal;
- denoising, at the one or more denoisers, the time reversed signal to generate a denoised time reversed signal, wherein the denoised time reversed signal includes near-zero phase error and near-zero phase delay;
- and
- generating an output signal based on adding the denoised signal and the denoised time revered signal.
A non-transitory computer-readable medium having stored thereon instruction code, wherein the instruction code is executable by one or more processors to perform operations comprising:
- denoising an input signal to generate a denoised signal, wherein the denoised signal includes near-zero phase error and near-zero phase delay;
- generating a time reversed signal of the input signal;
- denoising the time reversed signal to generate a denoised time reversed signal, wherein the denoised time reversed signal includes near-zero phase error and near-zero phase delay;
- and
- generating an output signal by adding the denoised signal and the denoised time revered signal.
