TRANSMIT/RECEIVE COMPENSATION IN SMART ANTENNA SYSTEMS

摘要

A radio communication system includes multiple antennas (204) and a processor (202) coupled to the multiple antennas (204). The processor (202) includes a probeless transmit/receive compensation component enabling the radio communication system to compensate for variations in transmit and receive paths while transmitting a signal. A transmit/receive compensation method includes, for each antenna in an antenna array (204), transmitting a known signal using the antenna while receive the transmitted signal using the other antennas in the antenna array (204), and calculating transmit/receive compensation based on the ratios between received signals and transmitted signals.
