    摘要: A method for determining a subscriber unit location in a communication system is provided. The method includes the steps of receiving a signal from the subscriber unit at a first base station, determining a first receive time of the signal based on a sequence of spreading symbols at the first base station, determining a first angle of arrival of the signal at the first base station, and determining the location of the subscriber unit from the first receive time, the first angle of arrival, and further predetermined information about the first base station. The signal is formed via modulation by the sequence of spreading symbols.

    摘要: A method and apparatus for determining the location of a communication unit in a CDMA system includes in a first embodiment, sending a location request via a spread spectrum signal to the subscriber (140), and receiving in return a subscriber signal including a response message showing a receive time of a particular symbol of the base's spreading sequence and a transmit time of a particular symbol of the subscriber's spreading sequence. The base (130), along with other receiving base(s) (140), also receives a predetermined symbol of the subscriber spreading sequence, and each determines a respective receive time of the predetermined symbol. The received information is then processed, along with known base location and delay information, to determine the subscriber location. If insufficient number of bases are capable of communicating with the subscriber, for example due to high loading/interference, auxiliary bases (121) are also provided for receiving from or transmitting to the subscriber.

    摘要: A method for interrupting a radio transmission in a quasi-duplex radio-frequency communication system. The method of the present invention includes the step of transmitting a signal (22), with periodically-occuring holes (24) therein, by a first communicatioin unit (10) to at least a second communication unit (12). The transmitted signal (12) includes an audio information portion (16) and information packets (23). Each information packet (23) specifies the time of occurence of the next hole (24). The second communication unit (12) initiates an interruption of the transmission made by the first communication unit (10) by transmitting an interrupt request signal (31) to the first communication unit (10) at a time specified by an information packet (23) received by the second communication unit (12). When the first communication unit (10) receives the interrupt request signal (31), it processes the interrupt request signal (23) to determine whether it complies with predetermined criteria. If the first communication unit determines that the interrupt request signal complies with the predetermined criteria, it transmits an acknowledgement signal allowing the second communication unit (12) to interrupt the transmission so that the second communication unit (12) may begin transmitting information to be received by at least the first communication unit (10).

    摘要: A portable communication device (10) is controlled by voice recognition circuitry (20) remote from the portable communication device. The portable communication device includes apparatus for producing and transmitting a parametric representation of voice commands. The remote circuitry (which could possibly be a base station, a mobile repeater, or simply a dedicated box, separate from the portable) produces control signals, responsive to the parametric representation of voice commands, for controlling the portable communication device.

    摘要: A communication unit (10) transmits a first signal (12) that has a plurality of holes (44) therein during the occurrence of which another communication unit may interrupt. A repeater (14) receives the first signal and transmits a second signal (16) comprising the information in the first signal, and a plurality of digital coded squelch words synchronized with the holes to indicate the location of at least one of the holes in the first signal (i.e., the time at which at least one of the holes will occur). In one embodiment, each hole occurs after each pair of coded squelch words, and accordingly the pairs of coded squelch words are marked to indicate the times of occurrence of holes in the first signal.

    摘要: After setting a base station to a transmit power level (12) which provides a signal at a subscriber unit having a target quality level, a fading characteristic of a communication channel between the subscriber unit and a base site is measured (13). The fading characteristic is then compared with a threshold value (14). The measuring (13) and comparing (14) are repeated until the fading characteristic crosses a threshold (15). Once the fading characteristic crosses the threshold for a receive Eb/No level that is representative of a e.g. static fading condition, the base transmit power that is transmitted to the subscriber is increased by a predetermined amount in anticipation of the need for an increased Eb/No for the case of a faded signal (61). The determination of the fading characteristic and threshold comparison may be performed at either the subscriber unit or the base station.

    摘要: A device and method for trading commodity options and futures related to an educational institution's non-rival athletic program to manage risks associated with producing collegiate athletic programs. In one version, the underlying asset of the options and futures contracts is an athletic prospect's obligation to participate in a non-rival athletic program at a particular institution in exchange for the opportunity for the athletic prospect to participate in academic and athletic programs within the institution. In a particular form, the underlying asset is a signed National Letter of Intent, a contract that obligates a prospect attending a particular institution to participate in that institution's non-rival athletic program. Revenues generated by options and futures contracts traded according to the device and method of the present invention can be used to further the institution's educational and athletic missions.

    摘要: A vehicle mounted mobile transceiver (11) communicates via a secondary mobile unit (51) with a short range portable unit (10). The portable unit (10) can be either a cordless microphone or a transceiver. The portable unit (10) allows a remotely positioned operator to transmit messages to a base station (13). To ensure security and reliable operation, the portable and vehicle mounted units use digitized codes for ID and instruction purposes. These codes are newly generated from time to time by the vehicle mounted unit and are imparted to the portable unit via a battery charging interface by modulating the battery charging signal with the reset and digital data signals. An improved remote squelch detect is also provided.
