SYSTEM AND METHOD FOR DETERMINING CHANNEL LOSS IN DISPERSIVE COMMUNICATION CHANNEL AT NYQUIST FREQUENCY

PROBLEM TO BE SOLVED: To provide a system for determining a loss in a communication channel.SOLUTION: The present invention includes receiving a signal from an output of a dispersive communication channel established between a transmitter and a receiver, determining normalized Nyquist energy of the signal transmitted along the dispersive communication channel established between the transmitter and the receiver, and generating a mapping table configured to identify a peaking value at or above a selected tolerance level at or near the Nyquist frequency for a signal received by the receiver based on the normalized Nyquist energy.
