Abstract: Disclosed are various embodiments for controlling an output power of a transmitter. Adjustment amounts for a transmitter to transmit at a desired power level are determined. For a predetermined time period, an actual power level of the transmitter is adjusted at a first adjustment rate. Upon an expiration of the predetermined time period, the actual power level is adjusted at a second adjustment rate, wherein the second adjustment rate is slower than the first adjustment rate.

Abstract: Disclosed are various embodiments providing carrier separation to effectuate a dual carrier operation of a wireless communication device. Processing circuitry may acquire a single carrier signal based on a determined time slot boundary, the single carrier signal comprising primary carrier data. The processing circuitry may receive a dual carrier radio frequency signal based on the determined time slot boundary, the dual carrier radio frequency signal comprising the primary carrier data and secondary carrier data. The processing circuitry may then generate a baseband dual carrier signal by demodulating the dual carrier radio frequency signal. The processing circuitry may separate the primary carrier data from the baseband dual carrier signal by filtering the baseband dual carrier signal. The processing circuitry may also separate the secondary carrier data from the baseband dual carrier signal by filtering the baseband dual carrier signal.

Abstract: In a method and system for audio level detection and control, an amplitude of an audio signal may be compared to a threshold and an attenuation applied to the audio signal may be adjusted based on the comparison. In instances that the amplitude of the audio signal is greater than or equal to the threshold the adjustment may comprise increasing a first attenuation factor until the amplitude of the audio signal is less than the threshold. The first attenuation factor may be subsequently decreased until the amplitude of the audio signal is greater than or equal to the threshold or until the first attenuation factor is equal to zero. The attenuation of the audio signal may be controlled via a digital gain circuit within the hardware audio CODEC, wherein an overall attenuation factor of the digital gain circuit is a sum of the first attenuation factor and a second attenuation factor.

Abstract: In a method and system for audio level detection and control, an amplitude of an audio signal may be compared to a threshold and an attenuation applied to the audio signal may be adjusted based on the comparison. In instances that the amplitude of the audio signal is greater than or equal to the threshold the adjustment may comprise increasing a first attenuation factor until the amplitude of the audio signal is less than the threshold. The first attenuation factor may be subsequently decreased until the amplitude of the audio signal is greater than or equal to the threshold or until the first attenuation factor is equal to zero. The attenuation of the audio signal may be controlled via a digital gain circuit within the hardware audio CODEC, wherein an overall attenuation factor of the digital gain circuit is a sum of the first attenuation factor and a second attenuation factor.

Abstract: Aspects of a method and system for WCDMA/HSDPA timing adjustment may include adjusting an uplink transmission timing of a signal for transmission by a large adjustment step, utilizing a plurality of smaller adjustment steps, to generate an adjusted transmission signal. The transmission signal may be upsampled to a rate corresponding to the smaller adjustment step, which may generate an upsampled transmission signal. An adjusted upsampled transmission signal may be generated by inserting one or more of the smaller adjustment steps via one or more extra samples into the upsampled transmission signal to generate a delay, or removing one or more samples from the upsampled transmission signal to generate an advance. The adjusted upsampled transmission signal may be filtered and downsampled to generate the adjusted transmission signal.

Abstract: In a method and system for frequency compensation in an audio CODEC, a filter in a hardware audio CODEC may be configured based on power consumption and based on a frequency response of an active output device to which the filter is communicatively coupled. The filter may comprise a plurality of filter stages, which may be, for example, biquads, and the filter may be configured by enabling or disabling one or more of the stages. In this manner, power consumption of the filter may be managed by enabling and/or disabling one or more stages. Configuration of the filter may be performed dynamically depending on whether one or more audio output devices may be active. In this regard, which output device is active and its frequency response may be determined and filter coefficients may be reconfigured upon a change in which output device may be active.
