Abstract

In telecommunication devices like power amplifiers for cellular systems the amplitude of a transmission signal has to be limited to avoid signal deterioration. The improve the effciency of such amplitude limiter the present invention proposes to fed the input sample sequence to an estimation filter (56, 57) to determine the actual signal overshoot over a predefined threshold value. By this a clipping control signal to adjust the amplitude of the transmission signal accordingly can be generated with higher accuracy.
