<p>The present invention uses newly received signal samples to update previously determined scatterer parameters, and therefore, reduces the processing effort required for characterizing scattering objects in a wireless channel. Broadly, the present invention determines a first set of scatterer parameters based on signal samples derived from signals received during one or more previous time intervals, and determines an updated set of scatterer parameters for a subsequent time interval based on the first set of scatterer parameters and the new signal samples. In one exemplary embodiment, the receiver uses a continuous sequential update process, e.g., a per-symbol-period inverse Prony process, to update the scatterer parameters. In another exemplary embodiment, the receiver uses an integrated Doppler approach to update the scatterer parameters.</p> |
