Abstract: A technique that includes providing a buffer to receive data from a processor of a wireless device in response to an active mode of the processor and selectively coupling an input terminal of a filter to the buffer based on a status of the buffer.

Abstract: A technique includes based on a processing time that is available to a wireless device during an upcoming time interval, selectively enabling and disabling logging by the wireless device.

Abstract: In one embodiment, the present invention includes a method for determining a level of a buffer that stores data samples. The level may be determined at a predetermined position of a data frame sequence. Based on the level of the buffer at this position, a vocoder and modem of a mobile station may be synchronized. One or both of the vocoder and modem may be adjusted to attain the synchronization. Thus a rate mismatch between the vocoder and modem may be resolved.
