Abstract

A peak power reduction method for wireless communication systems is proposed in which a constellation shaping is applied on input data symbols in order to reduce the peak power of the signal samples to be transmitted by the communication system. According to the invention, the symbols are modified using functions each representing the contribution of a symbol to the output signal samples of large magnitude.
