Abstract: An apparatus for generating a pilot pattern for data to be transmitted in an orthogonal frequency-division multiplexing (OFDM) based communication system, having a for allocating pilot symbols for a plurality of data streams to form a plurality of pilot clusters in the pilot pattern, wherein each of the pilot clusters includes ones of the pilot symbols, the ones of the pilot symbols being for respectively different ones of the data streams. The apparatus also includes a mechanism for moving at least one of the pilot clusters from a first location in the resource block to a second location in the resource block to generate a second pilot pattern, the first and second locations being symmetrical in time, and a mechanism for generating a third pilot pattern based on the first and second pilot patterns.
