Abstract

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