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 and estimates 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.

Abstract: Various types of data, and at various rates, may be arranged into a uniquely structured format for transmission. Data for transmission formatting may be speech data provided by a vocoder or different types of secondary traffic. The data is organized into frames of a predetermined time duration for transmission by a microprocessor. The data frames are organized, depending on the data, to be at one of several data rates. To transmit such a frame at a predetermined rate the data frame is received and a set of parity check bits and tail bits for the frame are generated in accordance with the frame rate. An augmented data frame including the parity check bits and the tail bits derived from the data frame is encoded and transmitted.

Abstract: The device has a considerable dynamic range and isapplicable for operation both in frecuency modulation mode and inmultilateral coded access mode. It has improved fast action andaccuracy and guarantees linear adjustment of the amplification atcomparatively wide frequency range. The device contains anamplifier (18) for receiving controliing and input signals whichreact to any changes of the signal power and control theamplification of the input signal to a level corresponding to thecontrol signal where the respective output signal is produced. Ameasuring circuit (20) is connected to the amplifier (18) for thedetermination of the level of the amplified input signal by alogarithmic scale from which the respective linear proportionalmeasuring signal is received. The device also includes anintegrator (22), receiving the measuring and the standard signalwhich is proportional to the desired level of the output signal.The integrator (22) effects the integration depending on thedifference in time between the measuring and the standard signaland generates the control signal in accordance with the resultfrom it.

Abstract: A power control system for a cellular mobile telephone system in which system users communicate information signals between one another via at least one cell site using code division multiple access spread spectrum communication signals. The power control system controls transmission signal power for each cellular mobile telephone in the cellular mobile telephone system wherein each cellular mobile telephone has an antenna, transmitter and receiver and each cell-site also has an antenna, transmitter and receiver. Cell-site transmitted signal power is measured as received at the mobile unit. Transmitter power is adjusted at the mobile unit in an opposite manner with respect to increases and decreases in received signal power. A power control feedback scheme may also be utilized. At the cell-site communicating with the mobile unit, the mobile unit transmitted power is measured as received at the cell-site. A command signal is generated at the cell-site and transmitted to the mobile unit for further adjusting mobile unit transmitter power corresponding to deviations in the cell site received signal power. The feedback scheme is used to further adjust the mobile unit transmitter power so that mobile unit transmitted signals arrive at the cell-site at a desired power level.

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.
