An adaptive channel interpolation method and apparatus for OFDM wireless communication systems that use reference symbol-assisted channel estimation is disclosed. A time frequency representation of a subframe having reference symbols scattered throughout is divided into parallelograms, wherein the vertices of each parallelogram are the reference symbols. The channel response of a data symbol at the center point of the parallelogram is estimated using two of the vertices from opposing vertices of the parallelogram.
