One embodiment of the present invention relates to noise control of one or
more signals. In one embodiment, impulsive-type noise events, such as
multipath noise events or pops, may be detected and suppressed to reduce
signal distortion. For example, in one embodiment related to a radio
receiver (100), a predictor (436) having an adaptive filter (402) is used
in combination with a fast attack slow decay mechanism (434) to provide
noise control signals (352, 358) which may then be used to suppress noise
events. In one embodiment, the fast attack slow decay mechanism includes
applying a wide bandwidth filter at the onset of a noise event to quickly
track variations in an error signal and applying a narrow wide bandwidth
filter a peak of the noise event is detected in order to smooth
variations in the error signal (410). This allows for improved
psycho-acoustic perception. In one embodiment, the radio receiver is a
mobile radio receiver.
