Abstract: 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 processi ng 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 provid es improved signal gain. The improved signal gain permits a reduction in transm it power and, accordingly, increased capacity of the CDMA system. Where the antenna system is to be remotely located from the signal processing equipmen t, separate units for the RF receiver/transmitter and the other signal processi ng 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.

Abstract: A communication 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 communication 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.
