Abstract: 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 CDMA base station 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.

Abstract: 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.

Abstract: In response to the base station receiving a received signal, the received signal having a first spread-spectrum signal and an interfering signal. An automatic gain control (AGC) circuit generates an AGC-output signal which is despread by a despreader and then processed as a received-power level. A power command signal is generated using a threshold test and the received-power level.

Abstract: 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.
