ABSTRACT:
Signals arriving from N channels are processed by an array of two-input, two-output decorrelation processors to produce N output channels in which the signals from each of the input channels are decorrelated from all of the other channels. The array of processors includes N-2 rows, each row containing N processors in a regular array having a form equivalent to a cylinder. The array of processors also includes a further last row containing N/2 processors, the outputs of which are the desired signals. An arrangement using a single row of N processors with switched feedback allows equivalent batch processing.
