Amplitude compression of signals e.g. for multiple carrier system, involves multiplying subcarrier data signals by factor M and data signal values

摘要

The method involves multiplying subcarrier data signals by a factor M. The data signal values, appropriate for their signal strength above a certain signal strength threshold value E, are set to a fixed value. A channel estimation for each subcarrier is accomplished and due to the signal strength distribution of the channel estimated values of the subcarriers that maximum signal strength as signal strength threshold value E is determined. From the signal strength threshold vales a constant of the multiplication factor can be calculated. An independent claim is included for a device.
