Abstract:
A method for configuring and initializing an equalizer, the equalizer equalizing a signal received over a propagation channel, the received signal having symbols, including a synchronizing signal and being formed by one or more rays including a dominant ray, the method comprising the operations of:(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, the equalizer having coefficients; (d) configuring the equalizer based on the multi-path intensity profile to deactivate some of the coefficients; and (e) initializing active coefficients of the equalizer based on the propagation channel response.
