Abstract: A method employed by a base station for controlling transmission power during the establishment of a communication channel utilizes the reception of a short code during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional access code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The power of the short code is quickly increased until the signal is detected by the base station. Once the base station detects the short code, it transmits an indication that the short code has been detected.

Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a radio carrier station over telecommunication lines for simultaneous transmission over a radio frequency channel as a code-division-multiplexed signal to a group of subscriber units. The radio carrier station receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The radio carrier station includes a plurality of CDMA modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a code division multiplexed signal. The RCS includes a system channel controller is coupled to receive a remote call. A radio frequency transmitter is connected to all of the modems to combine the code division multiplexed processed signals with the global pilot code signal to generate a code division multiplexed signal. The transmitter also modulates a carrier signal with the code division multiplexed signal and transmits the modulated carrier signal through a radio frequency communication channel to the subscriber units. Each subscriber unit includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the code division multiplexed signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the radio carrier station and the subscriber units, and system capacity management for maintaining a maximum number of active subscriber units for improved system performance.

Abstract: A pilot adaptive vector correlator for estimating channel-impulse response and for obtaining a reference value of received multipath signals in a spread-spectrum system. A code generator generates a plurality of replicas of a pilot-spreading-code signal, with each replica of the pilot-spreading-code signal having a different phase from other replicas in a plurality of replicas of pilot-spreading-code signals. Each correlator in a plurality of correlators uses a replica of the pilot-spreading-code signal with a different phase from the other correlators in the plurality of correlators. The plurality of correlators correlates the spread-spectrum signal with the plurality of replicas of the pilot-spreading-code signals. The plurality of correlators generates a noise-power level when a pilot-spreading-code signal is not in phase with a replica of the pilot-spreading-code signal, and a pilot signal-power level plus noise-power level when a pilot-spreading-code signal is in phase with a replica of the pilot-spreading-code signal. Using the detected-pilot signal and output signals from the plurality of correlators, a derotation-phaser circuit generates a derotation-phaser signal. Using the derotation-phaser signal, a correction circuit corrects the despread, multipath signals for effects of carrier-phase rotation.

Abstract: A device tracks multipath components of a spread-spectrum signal. The spread-spectrum signal has an associated chip code sequence. The device receives multipath components of the spread-spectrum signal. A first and second plurality of multipath components are despread about a center code phase. The first plurality is a sequence of multipath components prior to the center code phase and the second plurality is a sequence of multipath components after the center code phase. A first and second combined energy is determined from the first and second plurality of multipath components. A tracking delay is calculated based on a difference between the first and the second combined energies. The center code phase is adjusted by said tracking delay.
