    Abstract: A closed loop automatic gain control (AGC) circuit with high dynamic range capabilities having an amplifier circuit for receiving an input signal, which is susceptible to variations in signal power, and a control signal. The amplifier circuit is responsive to the control signal for amplifying the input signal at a gain level corresponding to the control signal so as to provide a corresponding output signal. A measurement circuit is coupled to the amplifier means for measuring logarithmic signal power of the amplified input signal and providing a corresponding linear measurement signal. An integration circuit is included for receiving the measurement signal, and a reference signal which corresponds to a desired signal power of the output signal. The integration circuit integrates with respect to time the difference between the measurement signal and the reference signal, and generates the control signal which corresponds to the result of the integration.

    Abstract: In a cellular telephone system a system for directing communications between a mobile user and cell-sites as a mobile user changes cell-site service areas. The mobile user includes an apparatus for, while in communication with another system user via one cell-site, determining a transition of the mobile user from the cell-site service area to the service area of another cell-site. The system includes circuitry responsive to the indication for coupling communications between the mobile user and the other system user via the new cell-site while the mobile user also remains in communication with the system user via the first cell-site. The system further includes apparatus responsive to the coupling of the communications between the mobile user and the other system user via the new cell-site for terminating the communications between the mobile user and another system user via cell-site with communications continuing between the mobile user and the system user via the new cell-site.

    Abstract: Exemplary embodiments are directed to power distribution among a plurality of receivers. A method may include requesting at least one receiver of a plurality of receivers within a charging region of a transmitter to modify an associated load resistance to achieve a desired power distribution among the plurality of receivers. The method may further include requesting each receiver of the plurality of receivers to modify an associated load resistance to achieve a desired total impedance as seen by the transmitter while maintaining the desired power distribution among the plurality of receivers.

    Abstract: Techniques to adjust the setpoint of a power control loop in a wireless communication system. The setpoint may be adjusted based on frame status indicative of erased/good decoded frames, one or more (typically soft) metrics indicative of the confidence in the decoded results, power surplus/deficit indicative of the difference between the received signal quality and the setpoint and a threshold Eb/Nt needed for the desired level of performance, or a combination thereof. The metrics include one of a re-encoded power metric and a modified Yamamoto metric. The setpoint may be adjusted in different manners and/or by different amounts depending on the above-noted factors. The techniques may be employed for forward and/or reverse links in CDMA systems.

    Abstract: In the present invention, the slave base station attains synchronization with the reference base station through messages transmitted from and received by a mobile station either in the soft handoff region between the reference base station and the slave base station or within a range which allows the mobile station to communicate with the slave base station. When the mobile station is not in communication with both the reference base station and the slave base station, then the round trip delay between the mobile station and the reference base station is measured by the reference base station. The reference base station communicates the PN code used by the mobile station over the reverse link to the slave base station. The slave base station acquires the signal from the mobile station and determines when the signal from the mobile station arrives. The slave base station then makes an estimate as to the length of the delay between transmission of a signal from the mobile station to the slave base station. Based upon these measurements and estimates, the slave base station determines the error which is present in the slave base station system time.
