ABSTRACT:
An apparatus and method are provided for discriminating noise in a received signal. The apparatus comprises a first signal processing means, a second signal processing means, a threshold generating means for generating a threshold value. The first signal processing means generates iteration signal samples and predicted iteration signal samples, compares the iteration signal samples and predicted signal samples to generate a predicted error parameter. The second signal processing means generates a threshold adjustment value based on generated successive iteration signal samples. A logic means logically treats the prediction error parameter, the threshold adjustment value and the threshold value to generate a noise indication value.
