Abstract
A method and for optimizing bit rate throughput in a digital communication system is provided. The method includes establishing a relationship between signal to noise ratio and plural symbol rates for a particular constellation size. The method also includes determining noise power spectral density (N(f)), wherein N(f) is determined during a silent period of line probing; determining X(f), wherein X(f) is determined by turning on a remote station transmit signal, after N(f) has been measured and determining residual echo E(f), wherein E(f) is determined by turning on a central station echo canceller.
