SIGNAL PROCESSING METHOD AND SYSTEM FOR BLIND SOURCE SIGNAL SEPARATION

摘要

The present invention relates to signal processing, and, in particular to a method and system for blind source separation which uses a measure of temporal predictability to identify a source signal from a mixture of such source signals. The temporal predictability of any signal mixture is defined to be less than that of its component source signal. The temporal predictability is used to recover source signals from a set of linear mixtures of source signals by finding an unmixing matrix that maximises the measure of temporal predictability signals. Accordingly, the method is fast.
