A method for determining the filter coefficients of a digital time domain equaliser for a multi carrier frequency signal

摘要

A vector space comprising all of the filter coefficients (heq,opt) for different interfering signals (w(n)) is provided, based on an acquired impulse response (hchan). A linear vector sub-space (popt) comprising all of the optimal filter coefficients (heq,opt) for different interfering signals (w(n) is established from said vector space using a vector space optimisation method. The filter coefficients (heq,opt) are established from the vector sub-space according to the current interfering signal (w(n) being detected, during ongoing data transmission and at the maximum transmission speed.
