A method of reducing a peak to mean amplitude ratio of a signal at an output of a pulse shaping filter, hereinafter referred to as the post-filtered signal samples, is provided, the said method comprising the steps of generating test signal data samples in dependence upon a plurality of discrete time signal samples representative of the signal before passing through the pulse shaping filter hereinafter referred to as the pre-filtered signal samples, and scaling the pre-filtered signal samples in accordance with the test data samples, thereby constraining the post-filtered signal samples to a predetermined threshold. |
