Zusammenfassung:	Systems and methods are described for the implementation of a receiver that includes a channel estimation block that uses known pilots to estimate the value of channel gain and phase at data subcarrier indexes. Time interpolation as well as an auto regression filter can be to estimate the channel gain and phase at the "missing" pilot indexes as well as frequency interpolation to estimate the value of the channel at data subcarrier indexes.
