ABSTRACT:
The channel estimates for the subcarriers are used to determine the signal strength distribution in the form of a cumulative histogram. The latter is used to determine, as a signal strength threshold value E, that maximum signal strength whose magnitude is less than or equal to the signal strengths of a predetermined number L of subcarriers which are to be limited, i.e. saturated, in the signal processing path. The signal strength threshold value E and a constant K are used to form a multiplication factor M with which the data signals are weighted or by which the data signals are multiplied, the L subcarriers being limited to a fixed value after multiplication.
