Abstract
A transmitter includes: a frame generator configured to generate a frame including a frame starting symbol, at least one data symbol and a frame closing symbol; a pilot and reserved tone inserter configured to insert pilots and reserved tones in at least one of the frame starting symbol, the data symbol and the frame closing symbol such that positions of the reserved tones do not overlap positions of the pilots in the at least one of the frame starting symbol, the data symbol and the frame closing symbol; and a transmitter configured to transmit the frame in which the pilots and the reserved tones are inserted, wherein the reserved tones are not used to transmit data in the frame.
Claims3
A receiving method comprising:
- receiving a frame from a transmitting apparatus;
- and
- processing the frame based on positions of tones for a peak to average power ratio (PAPR) reduction,
- wherein the frame comprises a preamble, at least one boundary symbol and data symbols;
- wherein the preamble comprises L1 signaling for the at least one boundary symbol and the data symbols,
- wherein the at least one boundary symbol comprises at least one of a symbol preceding a first data symbol of the data symbols or a symbol following a last data symbol of the data symbols,
- wherein the at least one boundary symbol comprises pilots inserted based on a first pattern and the data symbols comprise pilots inserted based on a second pattern,
- wherein the first pattern and the second pattern are different from each other, and
- wherein the pilots are not inserted at the positions of the tones in the at least one boundary symbol and the data symbols.
