Abstract: A communication device is described comprising a receiver configured to receive a plurality of first reference signal values in a first subframe of a radio frame structure and to receive a plurality of second reference signal values in a second subframe of the radio frame structure, wherein the first subframe and the second subframe are separated by one or more subframes of the radio frame structure, a first filter configured to filter the plurality of first reference signal values received in the first subframe to generate a first channel estimate, a second filter configured to filter the plurality of second reference signal values received in the second subframe based on the first channel estimate to generate a second channel estimate and a processor configured to process received signals based on the second channel estimate.
