摘要： In a communication device, a decoded audio signal is evaluated by a detection function (112). Two portions of the decoded audio signal spectrum are evaluated, a ringback band (206), and the remaining band(s). The signal strength in the ringback band is measured against a preselected ringback energy threshold level and the non-ringback signal strength is measured against a voice energy threshold level. Only if the ringback energy is above the ringback energy threshold level and the non-ringback band energy is below the voice energy threshold level will a ringback filter be applied to the audio signal.

摘要： A system, method and computer readable medium are provided for segmenting a cache that is shared by multiple processors. According to the method, a first segment of the cache is allocated to a first processor and a second segment of the cache is allocated to a second processor. An execution time of at least one task on the first processor is monitored. If the execution time of the at least one task is greater than an allowed execution time minus a predetermined margin, the size of the first segment of the cache that is allocated to the first processor is increased. In one preferred method, if the execution time of the at least one task is significantly less than the allowed execution time minus the predetermined margin, the size of the first segment of the cache that is allocated to the first processor is decreased.

摘要： A digital communications system (10) includes a transmitting apparatus (12) and a receiving apparatus (14). In addition to a primary information signal (16), messages and control signals (24) are communicated for use by the equipment. To avoid the use of dedicated frequency spectrum, control channel time slots, or the degradation of forward error correction of the encoded information signal, the transmitting apparatus determines the occurrence of a silence period (28) in the information signal, then inserts the message or control signal information into the silence period. The resulting composite signal is transmitted to the receiving apparatus where message and control information is removed for use by the receiving equipment, leaving the information signal intact.

摘要： An electronic device (110) provides equalization and/or compensation for a coupled audio accessory device (120). The audio accessory device (120) has a memory (220) that contains equalizer parameters (304, 308, 310, 314) which helps in characterizing its audio response or impact on audio signals within the electronic device (110).

摘要： A mobile communication device (102) receives information in a broadcast control channel (108) including a page message (108). The mobile communication device measures certain parameters (210) of the control channel, such as received signal strength, channel quality, and the present automatic gain setting. These parameters are scored and weighted (300) to produce a signal quality metric (314) to determine the duration of time the mobile communication device can remain in a low power state to conserve battery charge before checking for page alert message in the broadcast control channel next.

摘要： A portable communication device (104), such as a cellular telephone, is operable in a speakerphone mode. The communication device uses a digital communication scheme, and both receives and generates vocoded signals. The speakerphone provides half duplex operation to eliminate echo. When voice activity is detected, the device activates a speaker and mutes a microphone to avoid echo. When no voice activity is detected in the received signal, the speaker is muted and the microphone activated. To determine when speech activity is present in the received signal, a novel voice activity detection (VAD) algorithm is used which takes advantage of parameters provided as part of the received vocoded signal. The new voice activity algorithm includes calculating a staggered average of the frame energy value for a sequence of received frames, and determining if the staggered average value exceeds a threshold. The algorithm also includes adjusting the threshold level by basing the threshold level on the voicing value of the present vocoded frame.

摘要： The invention provides a method and system for dynamically estimating background noise. The system includes a portable communication device, a vocoder, and a voice activated detector. Based on information received by the portable communication device, the vocoder determines parameters related to incoming information including a voicing mode indicative of the periodicity of incoming information. The voice activated detector then compares the voicing mode to a threshold to determine whether a background noise estimate should be updated. The method includes the steps of: receiving a periodicity indicator and a current comfort noise level for an incoming voice frame; comparing the periodicity indicator with a predetermined threshold if the current comfort noise level is equal to a previous comfort noise level; and maintaining a background noise estimate if the periodicity indicator exceeds the predetermined threshold and revising a background noise estimate if the periodicity indicator does not exceed the predetermined threshold.
