ABSTRACT:
Systems and methods are disclosed for detecting temporary high level impairments, such as noise or interference, for example, in a communications channel, and subsequently, mitigating the deleterious effects of the dynamic impairments. In one embodiment, a preliminary decision is made on at least one signal transmitted over the communications channel. The at least one signal is remodulated and the impairment is determined using the at least one remodulated signal.
