TRANSMITTER, RECEIVER AND CONTROLLING METHOD THEREOF

摘要

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.

1. A transmitting apparatus comprising:
a frame generator configured to generate a frame for transmitting data, the frame comprising boundary symbols and data symbols; a pilot inserter configured to insert pilots in the boundary symbols and the data symbols; and a peak to average power ratio (PAPR) reducer configured to obtain positions of tones in the boundary symbols and the data symbols, and perform PAPR reduction using the tones, wherein the boundary symbols comprise a symbol preceding a first data symbol of the data symbols and a symbol following a last data symbol of the data symbols, wherein the pilot inserter inserts the pilots in the boundary symbols based on a first pattern, and inserts the pilots in the data symbols based on a second pattern different from the first pattern, and wherein the tones comprise carriers of the boundary symbols and the data symbols to which the pilots are not inserted.
