Patent ID: 8150324

Claim:
A method of clipping a baseband input signal, the method comprising: filtering a baseband input signal with a filter function Hi(f) to yield a filtered first signal; calculating a scaling factor, the scaling factor being derived from overshoots in magnitude of the filtered first signal over a threshold c; multiplying the filtered first signal by the scaling factor to yield a clipped signal; and filtering the clipped signal with an error frequency response HF(f) to yield a spectrally shaped clipped second signal wherein the method is executed in a multicarrier transmission system and a clipped second signal is formed from each baseband signal thereof, wherein each clipped second signal is converted by modulation into an intermediate frequency range, wherein the modulated intermediate-frequency signals are assembled into a summation signal to be clipped, and wherein the clipped summation signal is converted by modulation into a carrier-frequency output signal.
