System and Method for Determining Channel Loss in a Dispersive Communication Channel at the Nyquist Frequency

摘要

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 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.

主权项

1. A system for determining channel loss at the Nyquist frequency in one or more dispersive communication channels, comprising:
a transmitter; a receiver; an energy calculator configured to determine a normalized energy at the Nyquist frequency of a signal transmitted along a dispersive communication channel established between the transmitter and the receiver; and a mapping table generator 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 energy at the Nyquist frequency from the energy calculator.
