The present invention relates to communications for communication systems. The communication includes an antenna system which is coupled to an RF receiver/transmitter which in turn is coupled to other signal processing equipment including at least one modem for processing individual CDMA communications. Preferably the antenna system includes multiple antennas and delay units and outputs a combined signal having a known distortion imparted by the antenna system. The combined signal is in turn processed by the modem. The modem compensates for the known distortion in a manner which provides improved signal gain. The improved signal gain permits a reduction in transmit power and, accordingly, increased capacity of the CDMA system. Where the antenna system is to be remotely located from the signal processing equipment, separate units for the RF receiver/transmitter and the other signal processing equipment are provided so that the RF receiver/transmitter may also be remotely located along with the antenna system. Preferably a connecting cable of at least 20 feet is provided which supplies RF signals and DC power to the RF receiver/transmitter from the other signal processing equipment.

A CDMA subscriber unit includes an antenna system having multiple antennas and delay units for receiving a transmitted signal and outputting a combined signal having a known distortion imparted by the antenna system. The combined signal is in turn processed by a modem, which compensates for the known distortion in a manner which provides improved signal gain. The improved signal gain permits a reduction in transmit power and, accordingly, increased capacity of the base station. Where the antenna system is to be remotely located from related signal processing equipment, separate units for the RF receiver/transmitter and the other signal processing equipment are provided so that the RF receiver/transmitter may also be remotely located along with the antenna system.

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.

An apparatus for controlling transmission power during the establishment of a channel in a CDMA communication system utilizes the transmission of a short code from a subscriber unit to a base station 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 spreading code. The ramp-up starts from a power level that is lower than the required power level for detection by the base station. The subscriber unit quickly increases transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, it sends an indication to the subscriber unit to cease increasing transmission power. The use of short codes limits power overshoot and interference to other subscriber units and permits the base station to quickly synchronize to the spreading code used by the subscriber unit.

A multipath processor processes a plurality of groups of spread-spectrum signals. Each group has a plurality of spread-spectrum signals. A first plurality of spread-spectrum signals is despread within a first group to generate a first plurality of despread signals. The first plurality of despread signals are combined as a first combined-despread signal. A second plurality of spread-spectrum signals is despread within a second group to generate a second plurality of despread signals. The second plurality of despread signals are combined as a second combined-despread signal. The first and second combined-despread signal are combined as an output-despread signal.
