Abstract:
1. A method for use in an apparatus, the method comprising: determining a multi-path delay of a received signal; adjusting a bandwidth of a frequency interpolator as a function of the determined multi-path delay, wherein the frequency interpolator interpolates channel state information for subcarriers of the received signal, and wherein the adjusting step includes setting filter coefficient values of the frequency interpolator as a function of the determined multi-path delay, including changing a word length of at least some of the filter coefficient values as a function of the determined multi-path delay, wherein the word length of the at least some of the filter coefficient values increases as a function of the determined multi-path delay; and setting a dividing factor of a demapper as a function of the determined multi-path delay, wherein the demapper provides a received symbol stream recovered from the received signal.
