Abstract
Systems and methods are provided for controlling headroom of an amplifier (e.g., in a transmitter). A method comprises obtaining a target output power for a current interval and obtaining a target headroom for a subsequent interval. The method continues by adjusting, during the current interval, the power output capability of the amplifier based on the target headroom and adjusting the input power of an input signal based on the target output power, such that the output power of the amplifier is substantially constant during the current interval as the power output capability of the amplifier is adjusted.
