Abstract
In some embodiments, a wireless communication apparatus may include, but is not limited to, a pilot inserter, a segment divider, a phase rotator, and a first adder. The pilot inserter inserts first and second pilot symbols into a symbol stream. The segment divider divides into a plurality of segments a plurality of subcarriers. Each of the subcarriers is allocated with a respective one of the symbols included in the symbol stream into which the first and second pilot symbols have been inserted. The phase rotator performs, for each segment, a phase rotation to all of the symbols, except for a predetermined one of the first and second pilot symbols, included in the symbol stream. The first adder adds together signals corresponding to the subcarriers included in the plurality of segments to which the phase rotation has been performed by the phase rotator to generate a transmission signal.
