Title:
TRANSMITTING APPARATUS, RECEIVING APPARATUS, AND CONTROLLING METHODS THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/126171
Kind Code:
A1
Abstract:
Provided are a transmitting apparatus, a receiving apparatus and methods of controlling these apparatuses. The transmitting apparatus includes: a structurer configured to generate a transmission stream comprising an orthogonal frequency division multiplexing (OFDM) symbol and add signaling data to the transmission stream; and a transmitter configured to insert at least one pilot into the OFDM symbol, determine a number of active carriers to be included in a frequency spectrum, corresponding to the OFDM symbol into which the pilot is inserted, to exist in a preset spectrum mask, and map the OFDM symbol, into which the pilot is inserted, onto the active carriers of the determined number, and transmit the mapped OFDM symbol.
