摘要： Certain aspects of a method and system for delay matching in a rake receiver are disclosed. Aspects of one method may include compensating for a delay associated with at least one or both of the following in a rake receiver: a control channel and a data channel, prior to individual processing of received data by the data channel and individual processing of received data by the control channel. The data channel or the dedicated physical channel (DPCH) may be delayed with respect to the control channel, which may comprise, for example, the common pilot control channel (CPICH), by a particular time period.

摘要： An audio codec in a baseband processor may be utilized for mixing audio signals received at a plurality of data sampling rates. The mixed audio signals may be up sampled to a very large sampling rate, and then down sampled to a specified sampling rate that is compatible with a Bluetooth-enabled device by utilizing an interpolator in the audio codec. The down-sampled signals may be communicated to Bluetooth-enabled devices, such as Bluetooth headsets, or Bluetooth-enabled devices with a USB interface. The interpolator may be a linear interpolator for which the audio codec may enable generation of triggering and/or coefficient signals based on the specified output sampling rate. An interpolation coefficient may be generated based on a base value associated with the specified output sampling rate. The audio codec may enable selecting the specified output sampling rate from a plurality of rates.

摘要： Methods and systems for detecting, and controlling power for, an auxiliary microphone are disclosed. Aspects of one method may include a detection block intermittently enabling a bias circuit block to provide a bias signal to determine if an auxiliary microphone may be communicatively coupled to a mobile device. The detection block may process 1-bit digital samples received from the bias circuit bock to determine whether the auxiliary microphone may be communicatively coupled. The detection block may also process the 1-bit digital samples to determine if a button associated with the auxiliary microphone may have been pushed or activated.

摘要： Methods and systems for processing audio signals are disclosed herein. Aspects of the method may comprise controlling gain during multipath, multi-rate audio processing by generating a digital signal that is a product of an input digital signal and a gain coefficient derived from a lookup table, and coarse tuning the gain by bit-shifting the digital signal to generate a digital output signal. The gain may be fine-tuned utilizing a variable step size determined by interpolation. The gain coefficient may be partitioned into gain blocks, which may be twice a corresponding value in preceding gain blocks. The gain blocks may be partitioned into steps that represent particular gain values within a range associated with the gain block. The digital output signal may be ramped utilizing a linear interpolation of the gain coefficients over a number of samples of the input signal, where the number of samples is given as a power of two.
