  2. 1. Digital Compensation Techniques for Power Amplifiers in Radio Transmitters

    Author : Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear system; linearization; power amplifier; iterative learning control; digital predistortion; Volterra series;

    Abstract : Power amplifiers (PAs) are vital components in radio transmitters because they are responsible to amplify the low power communication signals to power levels suitable for transmission. Important requirements of PAs are high efficiency and linearity. Unfortunately, there is a tradeoff between efficiency and linearity. READ MORE

  4. 2. Digital Predistortion for the Linearization of Power Amplifiers

    Author : Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavioral model; Volterra series; nonlinear; digital predistortion; Doherty power amplifier; power amplifier; efficiency;

    Abstract : High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. READ MORE
