Abstract:
1. An adaptive equaliser for equalising received signals, the adaptive equaliser comprising: an equaliser coupled to equalise the received signals according to equalisation coefficients, to provide equalised signals having a representation of amplitudes and phases of the received signals; a detector for resolving data from the equalised signals; an asynchronous detection part for generating phase tracking information based on the resolved data and the equalised signals; an error estimator for estimating a phase corrected error based on the equalised signals, the phase tracking information, and the resolved data; an inhibit signal generator for generating an inhibit signal to inhibit updating of the equalisation coefficients, the inhibit signal representing a likelihood of the phase corrected error being accurate, determined according to the phase corrected error, and according to the equalised signals; and a coefficient generator for adapting the equalisation coefficients for the equaliser based on the received signals, and based on the phase corrected error, arranged to inhibit the adapting according to the inhibit signal.
