  • Patent number: 10333748
    Abstract: The present invention discloses an adaptive parameter adjustment method for a hybrid precoding millimeter-wave transmission system. The method includes the following step: interacting between a transmitter and a receiver for a number of radio frequency chains that need to be established. The receiver calculates, according to a received signal power at the time of established a different number of radio frequency chains and a total power consumption at the time of established the different number of radio frequency chains, the number of the radio frequency chains that need to be established. According to the present invention, under a condition of balancing power consumption and a rate, a number of radio frequency chains that need to be established is adaptively selected, so as to optimally configure power consumption and a transmission rate in a millimeter-wave transmission system.
