The tracking behaviour of a decision-feedback equalizer coupled to a carrier recovery loop, in the presence of a dynamic multipath fading activity has been studied. Minimum phase¿non minimum phase type fading transitions with notch depth variation rates up to 120 dB/s, and fadings sweeping accross the signal band at 300 MHz/s have been considered. Free interaction between the two adaptive devices is allowed. Simulated tap gains are compared to those theoretically obtained in order to justify the observed rms error increase which can eventually lead to the system outage. The extra freedom degree arising in the recovered carrier seems not to disturb the correct behaviour of the coupled system.
