Channel equalizer and corresponding operating method

A method of operating a channel equalizer for use with binary phase-shift keying (BPSK) modulation in a near field communication, NFC, device, the channel equalizer comprising a filter, an estimator and a synchronizer, and the method comprising:

• receiving, by the filter, an input signal from another NFC device and generating a filtered output signal;
• determining, by the estimator, filter coefficients to be used by said filter, wherein the estimator is configured to generate the filter coefficients using a well-behaved normalized constant modulus algorithm (wNCMA);
• determining, by the synchronizer, when to enable the channel equalizer and providing one or more corresponding control signals to the estimator, wherein the synchronizer is configured to detect reception of a data frame included in the input signal and to control the estimator such that channel equalization is only performed during reception the data frame.
