Abstract
A method of noise mitigation in a multi-carrier communication system includes receiving a signal from a decision device, determining whether synchronization symbol update is enabled, updating at least one of frequency-domain equalizer (FEQ) coefficients or digital echo canceller (DEC) coefficients in synchronization symbol periods if the synchronization symbol update is enabled, determining whether data symbol update is performed if the synchronization symbol update is not enabled, determining whether a flag associated with the signal is set if the data symbol update is not performed, and updating at least one of FEQ or DEC coefficients associated with the signal in synchronization symbol periods if the flag is set.
