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: A modem is configured for demodulating a communication signal associated with a unique code-division multiple access (CDMA) code. The modem includes an adaptive matched filter and a vector correlator. The vector correlator generates filter coefficients for the adaptive matched filter based on signal distortion determined by the vector correlator. The vector correlator has a processing capacity of at least eleven chips whereby the vector correlator compensates for a known phase distortion and for multipath distortion ascertainable within its processing capacity. The adaptive matched filter processes communication signals with the unique CDMA code using coefficients generated by the vector correlator.
