摘要： Aspects of a method and system for multi-band amplitude estimation and gain control in an audio CODEC are provided. In this regard, an audio signal may be filtered and delayed to generate one or more sub-band signals, a gain may be applied to each sub-band signal to generate one or more level adjusted sub-band signals, and the one or more level adjusted signals may be added to a delayed version of the audio signal.

A validity of a selected control channel may be determined based on consistency and a CRC, where the CRC may be derived from decoding a sub-frame. The calculating and selecting may be done for a first slot of a sub-frame for High-Speed Shared Control Channels.

摘要： In a hardware audio CODEC which processes audio signals from a plurality of inputs, voltage and/or power levels of the input audio signals may be adjusted such that the digitally adjusted levels are approximately equal for each of the plurality of inputs. The digital adjustment may comprise, for each audio sample of one of the input audio signals, adding the audio sample to one or more right shifted versions of the audio sample and selecting a portion of a summed audio signal resulting from the addition. The portion of the summed audio that is selected may be determined based on the type of audio content being processed. The one or more right shifted versions of the audio sample may be selected via one or more switching elements which may be controlled via a digital control word which may be dynamically generated.

摘要： A method to adapt channel quality indicator (CQI) reports from user equipment (UE) is provided. This involves first determining the presence of a high-speed shared control channel (HS-SCCH) signal. An estimated signal to noise ratio (SNR) is also determined. Next an SNR correction based on the presence or lack thereof of the HS-SCCH signal and the CRC checks for HS-SCCH and HS-DSCH signals are determined and applied to the estimated SNR. The CQI report is then generated based on the corrected estimated SNR. This CQI report which takes into account a corrected estimated SNR may then be used to adjust the HS-SCCH signal in an HSDPA telephony system.

摘要： A circuit for detecting when a microphone is connected to a microphone coupling includes a detection signal generator that asserts a microphone detection signal. A microphone power module supplies a microphone current to the microphone coupling in response to the assertion of the microphone detection signal. A microphone detection module detects when the microphone is not connected to the microphone coupling based on an impedance of the microphone coupling, wherein the microphone power module disconnects the microphone current from the microphone coupling when the microphone is not connected to the microphone coupling. In an embodiment, the circuit further detects when a microphone button is depressed.
