摘要： A single channel full duplex wireless communication system includes a processor, a transmitter, a receiver, a secondary transmission path, a combining element, a primary transmission feedback path and a secondary transmission feedback path. The transmitter transmits a transmission signal via a transmission path. The receiver receives a received signal via a reception path. The transmitter and the receiver utilize one channel to transmit and receive signals. The transmission signal causes self-interference. The processor estimates a first transfer function and feeds the secondary transmission path with the transmission signal adjusted by the first transfer function to reduce the transmission signal leaked to the reception path. The combining element combines the transmission signal with the adjusted secondary transmission path signal to remove the self-interference. The primary transmission feedback path output is modified by a second transfer function. The secondary transmission feedback path output is modified by a third transfer function.

摘要： A smart antenna system for communicating wireless signals between a mobile device and a plurality of fixed base stations using different channels and beams. The system comprises a control subsystem, a radio transceiver and an antenna subsystem, providing a plurality of beams. Each beam has a main lobe, one or more nulls, and one or more lateral and back lobes with at least some attenuation, so as to reduce interference. The system performs scanning of different combinations of base stations, channels and beams using one or more test links established with one or more of the fixed base stations. The test links use at least some of the different channels and the different beams, select a first combination of base station, channel and beam based on the scanning, and establish a first operating link for transmitting a wireless signal to the selected base station using the selected channel and beam.
