摘要： 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.

摘要： 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.

摘要： The present invention provides a base station architecture that is modular in configuration, lowering the initial cost of implementing a new CDMA telecommunication system for a defined geographical region while allowing for future capacity. The scalable architecture is assembled from a digital base station unit that is configured to support a plurality of simultaneous wireless calls connecting to a conventional public switched telephone network. For initial startup, two base station units are deployed for redundancy in case of a single failure. Additional base station units may be added when the need arises for extra traffic capacity. If sectorization is required, the base station units may be directionally oriented. Coupled to and remote from each base station unit are two amplified antenna modules that contain an omni-directional or an external directional antenna, a high power RF amplifier for transmitted frequencies and a low noise amplifier for received frequencies. A separate power supply module capable of supporting two base station units provides continued service in the event of a mains power outage.

摘要： A self-interference canceller (SIC) is incorporated into a transceiver to reduce or eliminate modem jamming when a transmitter in the transceiver transmits at high power levels. The SIC is configured to receive at a first input a transmitter noise reference signal including a self-interfering signal component generated by the transmitter, to receive at a second input a corrupted signal including the self-interfering signal component and a desired signal component generated by the transmitter, and to output a correction signal that resembles the self-interfering signal component. The correction signal is subtracted from the corrupted signal to generate a processed signal that is input to the modem. The SIC may be disabled when the output power of the transmitter is at a level below a predetermined threshold. The invention may be applied to a multi-radio access technology (RAT) transceiver.
