Abstract
A method for pilot design for data to be transmitted by an orthogonal frequency-division multiplexing (OFDM) based communication system, the data being represented by a plurality of OFDM symbols. The method includes allocating pilot symbols for a data stream to be included in ones of the OFDM symbols; and performing a frequency shift on at least one of the OFDM symbols, to reduce frequency distance disparities among the pilot symbols.
