Abstract
A method and a system for configuring and initializing an equalizer. The equalizer equalizes a signal received over a propagation channel. The received signal includes symbols, a synchronizing signal and is formed by one or more rays including a dominant ray. The method comprising the following: (a) generating a multi-path intensity profile of the propagation channel from the received signal; (b) determining an arrival time of the dominant ray and a propagation channel response corresponding to the arrival time based on the multi-path intensity profile; (c) decimating the received signal synchronously with the arrival time of the dominant ray to provide signal samples to the equalizer; (d) configuring the equalizer based on the multi-path intensity profile to deactivate some of the coefficients of the equalizer; and (e) initializing active coefficients of the equalizer based on the propagation channel response.
