Transmitter & Receiver Clipping Mitigation in DMT Transceivers

Two new methods for clipping mitigation in DMT transceivers are presented. The first method applies to the transmitter and spectrally shapes the clipping noise in order to increase the signal-to-noise ratio within the signal bandwidth. The second method applies to the receiver and can be implemented by design of pipeline A/D converters. The two methods are independent and can therefore be used separately or combined together without extra features. Both methods improve the overall system performance and relax the constraints of the implementation complexity of the analog front-end.
