Abstract: A device implementing adaptive gain table selection based at least on coexistence signaling may include at least one processor circuit. The at least one processor circuit may be configured to identify that a packet is scheduled to be received by a receiver and retrieve at least one transmission indicator that indicates whether at least one transmitter is transmitting, where the at least one transmitter is collocated with the receiver within a device. The at least one processor circuit may be further configured to select a first gain table for reception of the packet by the receiver when the at least one transmission indicator indicates that the at least one transmitter is transmitting, otherwise selecting a second gain table for reception of the packet by the receiver. The at least one processor circuit may be further configured to apply gain to the receiver based at least on the selected gain table.

Abstract: Systems and methods are described for enhancing the audio quality of an FM receiver. In embodiments described herein, a stop band noise signal is extracted from an L+R or L?R signal produced by an FM stereo decoder. A channel quality measure is calculated based on the stop band noise signal and is used to control whether a pop suppression technique is applied to the L+R signal. The channel quality measure and the stop band noise signal are also leveraged to perform single-channel noise suppression in the frequency domain on the L?R signal and on the L+R signal. The channel quality measure is also used to control the application of a fast fading compensation process that replaces noisy segments of the L?R and L+R signal with replacement waveforms generated via waveform extrapolation.

Abstract: Systems and methods are described for enhancing the audio quality of an FM receiver. In embodiments described herein, quadrature L?R demodulation is applied to a composite baseband signal output by an FM demodulator to obtain an L?R noise signal. A channel quality measure is calculated based on the L?R noise signal and is used to control whether a pop suppression technique is applied to an L+R signal obtained from the composite baseband signal to detect and remove noise pulses therefrom. The channel quality measure and the L?R noise signal are also leveraged to perform single-channel noise suppression in the frequency domain on an L?R signal obtained from the composite baseband signal and on the L+R signal. The channel quality measure is also used to control the application of a fast fading compensation process that replaces noisy segments of the L?R and L+R signal with replacement waveforms generated via waveform extrapolation.
