The invention relates to a method for amplifying a carrier signal (CS) by using a power amplifier (PA), the power amplifier (PA) is feed with a supply voltage (PASV) of a power supply (SMPS). The method comprises the step of adapting a value of the supply voltage (PASV) to a value related to a mean signal power of an input signal (DS) of a power amplifier system (PAS).

Method for amplifying a signal by a power amplifier, power amplifier system, device, computer program product, and digital storage medium thereof

A receiver for a digital communication signal has a first decision gate (DGa), which has a first decision threshold (xd) for outputting a first decision signal, a second decision gate (DGb), which has a second decision threshold (xm) for outputting a second decision signal, a counter (CNT) for counting events where the first and second decision signals of the first and second decision gates (DGa, DGb) differ from each other, and a controller (PROC) capable of controlling the decision thresholds of said first and second decision gates in accordance with count values delivered by said counter. The controller (PROC) determines an initial decision threshold value by performing a statistical analysis of the received signal and setting the decision threshold such that the distribution of logical '0' and logical '1' in the decided signal corresponds to the expected distribution, which is in typically 50%/50%.
