ABSTRACT:
A data hopping device is provided with a hopping generation unit and a data selection unit, the hopping pattern generation unit generating a predetermined hopping pattern, and the data selection unit outputs a plurality of subcarrier transmission signals corresponding to respective subcarriers, by receiving transmission data and outputting only the data carried in the subcarrier designated by the hopping pattern as the subcarrier transmission signal, while maintaining the other subcarrier transmission signals at a zero output level. An inverse Fourier transform device subjects the entirety of subcarrier reception signals output from the data selection unit to inverse Fourier transform and outputs frequency-hopped spread-spectrum transmission signals.
