摘要

A method with low complexity and a slight delay and a device in broadband - communication systems are used for protecting and transmitting the sides volume information on peak value - to - mean value - duty ratio (papr) - reduction parameter related. The sides volume information is coded by means of an error-correcting code and by means of a plurality of reserved transmitted subcarriers. The modulation of the encoded sides volume information about the reserved sub-carriers is separately without carried out again - carrying out the data modulation. This reduces the invention and dramatically the implementation complexity. The determination of the specific parameters for papr - reduction may be mounted on the papr - level of the data modulated signal with a slight reduction in the papr - reduction in power is based on the, or it may be from the transmitted signal, with no reduction in the papr - reduction in power be based.
