Abstract
Multi-carrier transmission system comprises transmitter including acquisition unit configured to acquire 2(m: a natural number) modulated signals including no-information signals which are failed to be used for information transmission and 2(n: a natural number, n<m) signals, acquisition unit subjecting modulated signals to inverse discrete Fourier transform to obtain transformed signals, no-information signal included in Lmodulated signal of modulated signals being used as first no-information signal of no-information signals, every Kmodulated signal of modulated signals that is counted from first no-information signal being used as no-information signal (K: a natural number, L: an integer, K=2, 0≦L≦K−1), and transmission unit configured to transmit transformed signals, and receiver including receiving unit configured to receive the transformed signals, and detection unit configured to detect synchronization timing based on at least one no-information signal included in the transformed signals.
