METHOD AND CONFIGURATION FOR IMPROVING THE DYNAMIC RANGE OF AN ADAPTIVE RECURSIVE NETWORK FOR PROCESSING DISCRETE-TIME SIGNALS

摘要

In a method and configuration for improving the dynamic range of an adaptive recursive network for processing discrete-time signals, gradient signals are formed from output signals of the network with respect to network parameters. The output signals of the network are compared with set-point signals to form differential signals. Signals of a signum function of the gradient signals are formed. The signals of the signum function are multiplied with the differential signals to form correction signals proportional to the product of the signals of the signum function and the differential signals.
