Abstract: A Faster-Than-Nyquist (FTN)-based transmitting apparatus segments an input data bit string into a plurality of partial bit strings, simultaneously channel-encodes each of the plurality of partial bit strings, simultaneously modulates each of the plurality of channel encoded bit strings to generate a plurality of modulation symbol sequences, and then pulse-shapes and transmits the plurality of modulation symbol sequences at a speed faster than a Nyquist rate.

Abstract: In an orthogonal frequency division multiplexing (OFDM) wireless communication system, when path delay information is received from a reception apparatus through a return path after data transmission, a length of a cyclic prefix included in a transmitted signal is adjusted on the basis of a delay value included in the path delay information.
