摘要:
A method (200) for improving quality of output audio (126). The method can include detecting an output acoustic signal (128) and generating a receive audio signal (134) based, at least in part, on the detected output acoustic signal. A frequency domain representation (140) of the receive audio signal can be compared to a frequency domain representation (138) of a source audio signal (124) from which the output acoustic signal is generated. At least one distortion signal (142) in the receive audio signal can be identified, and the source audio signal can be selectively equalized to reduce an amplitude of the source audio signal at a frequency that correlates to the distortion signal.
摘要:
A method (400, 500) of identifying a route traveled. The method can include, while traveling away from an initial location (115), detecting a unique identifier for each of a plurality of wireless communication devices (125) along the route. The method also can include presenting an indicator (210) that indicates a relative distance from at least one of the wireless communication devices while traveling toward the initial location. Detecting the unique identifier for each of the plurality of wireless communication devices can include detecting a media access control (MAC) identifier or an Internet protocol (IP) address for at least one of the communication devices.
摘要:
A system and method of retrieving dispatch call information from a dedicated database by using interconnect call information. Interconnect call information from an interconnect communication system is obtained. The information identifies a target dispatch subscriber unit in a dispatch communication system. A request is received from a source dispatch subscriber unit. The request includes the interconnect call information. The interconnect call information identifying the target dispatch subscriber unit is extracted from the request. The interconnect call information of the target dispatch subscriber is related to unique dispatch call connection information of the target dispatch subscriber in a dedicated database. The unique dispatch call connection information concerning the target dispatch subscriber unit from the dedicated database in the dispatch communication system is retrieved using the extracted interconnect call information from the request.

A quadrature modulated transceiver (102) is used to generate a constant envelope angle modulated signal for communications. To produce the required feedback when operating in the constant envelope mode, an orthogonal frequency division multiplexed receiver (136) is used.
摘要:
A method for managing information signal distribution in a communication system (100) includes transmitting a signal containing information configured according to a first media format from a first communication device (104) to a second communication device (110). At least one of the two devices (104, 110) monitors at least one operating characteristic of a depletable power supply (318) sourcing electrical energy for the second device (110). When a level of the monitored operating characteristic falls below a predetermined threshold, the first communication device (104) outputs the information to the second communication device (110) according to a second media format that requires less power consumption to process than does the first media format. Alternatively, under such circumstances, the first communication device (104) may output the information to a media output device other than the second communication device (110).
摘要:
A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

A mobile communication device (202) outside the service area of a communications network 210 in need of satellite positioning assistance information to perform a location determination (308). The mobile communication device receives the assistance information from a peer mobile communication device (204, 206) over a direct link.
摘要:
A communication device (100, 200) capable of transmitting information provides the means for regulating the temperature (116) of one or more heat-sensitive modules or components (160) of the communication device through the adaptive and dynamic control of the flow of transmissions by the communication device, thereby eliminating the need for stored thermal profiles of heat-sensitive modules of the communication device. In addition to the heat-sensitive module(s), the communication device has a multi-logic controller block (110) and a transmission flow control block (140). The multi-logic controller block (110) receives the temperature of the heat-sensitive module (116) and a first control clock (112) and utilizes multi-value logic to generate a flow control signal having hysteresis (126). The flow control block (140) is coupled to the multi-logic controller block (110) and the heat-sensitive module(s) (160) and operates to generate a transmission control signal adapted to control transmission of information by the communication device in accordance with the flow control signal (126) and a second control clock (142) provided to the flow control block (140).
摘要:
A method (100) for limiting transmission power of a communication device (600) having a plurality of transceivers (610, 615). The method can include determining a desired maximum transmission power and determining a plurality of power contribution factors. Each of the power contribution factors can be associated with a respective one of the transceivers. The method also can include determining an expected transmission power based on, at least in part, a sum of the power contribution factors. Further, responsive to the expected transmission power exceeding the desired maximum transmission power, the power contribution for at least one of the transceivers can be selectively reduced or terminated.
