A communications circuit includes a filter module with a sampling window, a control module, and an input buffer. The control module has a ray parameter interface to obtain information regarding significant ray changes that make it desirable to re-position the sampling window. The control module determines re-positioning parameters, responsive to this information, which reflect the re-positioning of the sampling window. The input buffer obtains samples of a received signal and outputs received signal data to the filter module. The filter module obtains the re-positioning parameters from the control module, and the filter module and control module temporally re-position the sampling window in duration and/or location in accordance with the re-positioning parameters, and output a filtered chip.
