  • Method and apparatus for controlling a TX power amplifier
    Patent number: 7489908
    Abstract: A method and an apparatus for controlling a TX power amplifier are provided in the present invention. The invention is applied for generating a power control curve in a power variation area to control the power variation for signal transmission when the TX power amplifier transmits the data during two continuous time slots, which are a first time slot and a second time slot, respectively have a first transmission power value K1 and a second transmission power value K2. The invention is aimed at producing a concave inter-ramp control curve in a inter-ramp division of the power variation area for controlling the power variation of the TX power amplifier, where the power for signal transmission is transformed from the first transmission power value K1 to the second transmission power value K2.
    Type: Grant

  • Method and apparatus for controlling a TX power amplifier
    Patent number: 7489909
    Abstract: A method and an apparatus for controlling a TX power amplifier are provided. The method is for generating a power control curve in an inter-slot region between two continuous or adjacent time slots, which respectively have different modulation types. The method and apparatus produces a concave inter-slot ramp control curve for reducing the power of the TX power amplifier in the inter-slot region, where the power for signal transmission is transformed from a first power value K1 to a second power value K2. The method and apparatus further estimates a transient period of the concave inter-slot ramp control curve, during which modulation switching of the TX power amplifier may occur.
