IMPROVING PERFORMANCE OF DSL MODEM UNDER IMPULSE NOISE

摘要

Improving performance of DSL modem under impulse noise is disclosed. A method of improving a performance of a digital subscriber line (DSL) modem having an impulse noise of long duration includes assigning a value to each of framing parameters based on a rate adaptation algorithm (304) which considers a signal-to-noise ratio (SNR) of a channel coupled to the DSL modem and a number of constraints applied to the DSL modem. The method also includes generating another set of values of the framing parameters through maximizing an impulse noise protection (INP) (312) of the DSL modem while meeting the number of constraints based on a limited set of possible values of the redundancy bytes per Reed Solomon codeword (Rp) of the framing parameters and a limited collection of possible values of the interleaver depth (Dp) of the framing parameters.
