摘要： A method and apparatus receives a symbol and subdivides (720) the symbol into a plurality of fragments. The method and apparatus perform (704) for the plurality of fragments a plurality of correlations with at least one possible symbol value, thereby producing a plurality of complex values corresponding to each fragment and further corresponding to the at least one possible symbol value. From the plurality of complex values a plurality of overall Fourier transforms are computed (706) across a frequency range, and a peak value in the plurality of overall Fourier transforms is located (708). The symbol is then determined (710) from the peak value.

摘要： A communication system (100) for dynamically selecting transmitters (115) for message transmission includes the transmitters (115) for sending transmission signals and a portable messaging unit (105) for receiving the transmission signals, calculating signal strengths of the transmission signals, and transmitting a signal indicative of the signal strengths. A controller (110) receives the signal and determines therefrom carrier-to-interference (C/I) values indicative of relative strengths of the transmission signals received by the portable messaging unit (105). Prior to message delivery, the controller (110) determines a selected transmitter (115) for transmitting a message to the portable messaging unit (105). The selected transmitter (115) is associated with a lowest C/I value that is chosen from the C/I values and that exceeds a C/I threshold value.

摘要： An apparatus comprises a radio frequency (RF) signal source; and a controller configured to adjust power of the RF signal source based on a detected parameter. In one embodiment, the apparatus further comprises a proximity sensor configured to determine proximity of the RF signal source to live tissue, and the detected parameter is the proximity determined by the proximity sensor. The RF signal source may be an RF antenna. The controller may be configured to reduce the power of the RF signal source when the proximity is less than a predetermined threshold value. The controller may be configured to reduce the power to a predetermined reduced power level.

摘要： A system and method for complete message delivery to a multi-mode communication device is presented. The communication device is adaptable to communicate with one or more carrier networks and one or more data networks. When a new message is received for the communication device, a message notification is sent to the device via a first network. The communication device parses the message notification and retrieves the complete message via a second network. Alternatively, the message notification may be delivered and the complete message may be retrieved via the same network.

摘要： A wireless communication system receives (402) a communication specifying a portable subscriber unit (122) for which the communication is intended, and further indicating an originator location at which an originator of the communication is positioned. The system determines (404) a recipient location at which the portable subscriber unit is positioned. The system then calculates (406) a distance between the originator location and the recipient location, and routes (412) the communication to the portable subscriber unit when the distance meets a distance criterion.

摘要： Sub-areas (506) within a coverage area of a wireless communication system are defined (702), and transmitters (502, 504) are positioned within the sub-areas. A memory (212, 314), in at least one of a subscriber unit (122) and a controller (112) of the system, is programmed (706) with unique transmitter identifiers (414) and corresponding transmitter locations; and a locator signal (406) is periodically transmitted (708) from the sub-areas during time slots (408) coordinated such that, within a sub-area, no more than one transmitter transmits during each time slot. The locator signal includes one of the unique transmitter identifiers for identifying the transmitter sending the locator signal. The subscriber unit monitors (710) the locator signal to determine propagation delays between the subscriber unit and the transmitters received; and one of the subscriber unit and the controller estimates (712) the location of the subscriber unit from the propagation delays and the transmitter locations corresponding to the unique transmitter identifiers received.

摘要： At least two subsets (204, 208) of simulcast transmitters are defined (802) that produce differing simulcast distortion characteristics at a receiver (210), and a message is sent (806) in a simulcast transmission from one of the at least two subsets. The message is then repeated (808, 810, 806) in a simulcast transmission from another of the at least two subsets, until all of the at least two subsets have transmitted the message.
