Method for limiting signal and transmitter
Abstract:
The invention relates to a method and a transmitter for limiting a signal at chip level. The transmitter limiting the signal at chip level comprises means (704) for determining a limiting signal from a transmissible signal filtered using a pulse shaping filter, the transmitter comprises means (704, 710, 712) for determining an error signal using the transmissible signal and the limiting signal, the transmitter comprises means (720) for generating a limited transmissible signal by reducing the error signal filtered using the filter matched to a chip pulse waveform from the transmissible signal and the transmitter comprises means (722, 724) for filtering the limited transmissible signal using the pulse shaping filter.
