| 主权项 | 1. A wireless transmission system which transmits and receives a single carrier modulated signal between a transmitter and a receiver that are coupled through a wireless transmission path, wherein the transmitter comprises a spectrum division filter bank that includes a Fourier transform unit converting the single carrier modulated signal to a frequency domain, a frequency allocation unit generating from the single carrier modulated signal in the frequency domain a plurality of sub-spectrum signals, each of which is arranged at a predetermined frequency position, and an inverse Fourier transform unit converting the sub-spectrum signals to time domain to produce a time domain signal, the transmitter using the time domain signal subjects the plurality of sub-spectrum signals arranged in spectra to a direct spectrum division transmission, and the receiver comprises a spectrum combination filter bank extracting the plurality of sub-spectrum signals from received signals arranged in spectra and subjected to the direct spectrum division transmission to combine the sub-spectrum signals into an original single carrier modulated signal. | ||
