Abstract
A method for channel equalization of received data includes steps of: receiving the received data in a received data packet; calculating filter setting coefficients for an input filter and calculating equalizer setting coefficients for an equalizer; setting the input filter using the filter setting coefficients and setting the equalizer using the equalizer setting coefficients; equalizing the received data using the input filter and using the equalizer; determining channel parameters for the transmission channel from the received data Xk; storing the channel parameters in a data field; and performing the step of calculating the filter setting coefficients for the input filter and calculating the equalizer setting coefficients for the equalizer by performing a GIVENS rotation of the data field.
