Abstract
A transmitting apparatus may comprise a symbol mapper; a first DFT and a second DFT performing DFT spreading on symbols mapped in the symbol mapper; and a subcarrier mapper mapping symbols which are DFT-spread in the first DFT and the second DFT to subcarriers, wherein the first DFT performs DFT spreading on all resource blocks to be transmitted when a total size of the resource blocks to be transmitted is a size which can be processed by the first DFT, or the first DFT performs DFT spreading on as many resource blocks among the resource blocks to be transmitted as the first DFT can process and the second DFT performs DFT spreading on the rest of the resource blocks to be transmitted when a total size of the resource blocks to be transmitted is not a size which can be processed by the first DFT.
