Abstract:
The invention is related to a communication terminal, comprising: means (618) for creating at least one channel matrix assuming predetermined interfering signals as a part of a desired signal; means (618) for dividing the at least one channel matrix into multiple sub-matrices; means (618) for diagonalizing the sub-matrices by using a transformation matrix; means (618) for forming at least one block-diagonalized matrix using diagonalized sub-matrices; means (618) for inverting the at least one block-diagonalized matrix; and means (618) for generating channel equalizer coefficients by using at least one inverted block-diagonalized matrix.
