ABSTRACT:
A method applied to an equalizer includes receiving an input data-stream having a training sequence component with a first number of symbols and a data component with a second number of symbols, wherein the first number plus the second number equals a third number; when a symbol number is not greater than the first number, training the training sequence component to generate a first trained coefficient set; when the symbol number is between the first number and the third number, recycling the training sequence component to generate a recycled training sequence component, and training the recycled training sequence component to generate a second trained coefficient set; storing the input data-stream to generate a delayed input data-stream when the symbol number is not greater than the third number; and applying the second trained coefficient set to the equalizer when the symbol number is greater than the third number.
