发明名称 Shadow filter system for quasi-underdetermined blind adaptive MIMO filtering
摘要 <p>The method involves evaluating received mixed signals (9) to determine a current scenario in which a signal source is active. Applicability of filter coefficient sets is determined for the scenario and compared with applicability of stored pattern-filter coefficient sets to determine one of the filter coefficient sets that is best suitable for the scenario. Adaptation of the filter coefficient set is performed, when the filter coefficient set is best suitable for the scenario. The mixed signals are multiple-input/multiple-output (MIMO)-filtered to produce multiple component signals (7). Independent claims are also included for the following: (1) a computer program having a set of instructions to execute a method for signal processing of multiple received mixed signals for producing multiple component signals for different scenarios (2) a digital storage medium with a computer program having a set of instructions to execute a method for signal processing of multiple received mixed signals for producing multiple component signals for different scenarios (3) an apparatus for signal processing of multiple received mixed signals for producing multiple component signals for different scenarios, comprising a multiple-input/multiple-output (MIMO)-filter device.</p>
