ABSTRACT:
A clipping protection scheme for a discrete multi-tone (DMT) digital subscriber loop modem telecommunications system determines the occurrence of clipping by checking the overflow bits in the IFFT status register. The transmitter then sends a predefined data stream to notify the receiver of the event, and then breaks the data into two frames for consecutive transmission to the receiver.
