Adaptive MIMO filtering in dynamically adjusted transformation areas

摘要

The method involves performing temporal and spatial transformation of input signals and desired output signals. A coefficient matrix is formed according to a relation of correlation matrices of the input signals or the input and output signals in a spatiotemporally transformed area. The correlation matrices are described using spatial transformation matrices according to a relation of corresponding correlation matrices with analog block structures in a temporally transformed area. The transformation matrices are optimized such that the correlation matrices are respectively block-diagonal. An independent claim is also included for a device for adaptive multiple-input and multiple-output (MIMO) filtering in dynamically adapted transformation areas, comprising a block for temporal transformation of input signals.
