  • Publication number: 20060046784
    Abstract: A multiple antenna control mechanism for wireless analog communications is disclosed. The control mechanism includes an antenna switch unit, a receiver unit, and a control unit. The antenna switch unit has multiple sets of reception antennas and associated low-noise amplifiers, and a single-pole-multiple-throw RF switch. It receives a wireless by transmitted RF signal that is carrying analog signals. The RF signal is amplified (and down-converted to an intermediate frequency), filtered, and demodulated by the receiver unit. The resulting RF/IF signal is then fed to the control unit for comparison, analysis and identification. When the reception signal quality is poor, the control unit signals the antenna switch unit to change to another reception antenna for maintaining good reception conditions.
