摘要： A modulation apparatus performs modulation in which a signal wave form is positioned at the front part of an entire symbol duration or the latter part of the entire symbol duration based on a first bit of the bit information to generate a modulation symbol including a silent signal duration in which there is no signal waveform. Particularly, the method delays a signal corresponding to a quadrature-phase signal axis by a predetermined time, thereby cancelling a phase difference between symbols.
