Abstract
A method is provided. The method includes receiving a carrier signal and analyzing the received carrier signal to identify at least one of a static multipath delay and a dynamic multipath delay in the signal. The method also includes configuring an equalizer based upon the at least one of the static and dynamic multipath delays.
Claims16
A method, comprising:
- receiving a carrier signal;
- analyzing the received carrier signal to identify at least one of a static multipath delay and a dynamic multipath delay in the received carrier signal;
- and
- configuring an equalizer based upon the at least one of the static and dynamic multipath delays,
- wherein the configuring the equalizer comprises estimating a required number of taps of the equalizer to equalize the at least one of the static and dynamic multipaths, and partitioning the required number of taps into first and second set of taps;
- wherein the first set of taps is to equalize the static multipath delay and the second set of taps is to equalize the dynamic multipath delay and wherein the configuring the equalizer comprises determining a position for each of the first and second set of taps of the equalizer.

A communication module, comprising:
- a receiver to receive a plurality of carrier signals;
- a channel estimator to analyze each of the plurality of the carrier signals to identify at least one of a static multipath delay and a dynamic multipath delay in the carrier signals;
- and
- an equalizer having a plurality of taps, wherein the equalizer is configured based upon the at least one of the static and dynamic multipath delays;
- wherein the equalizer comprises a first set of taps to equalize the static multipath delay and a second set of taps to equalize the dynamic multipath delay and wherein configuring the equalizer comprises determining a position for each of the first and second set of taps of the equalizer.
