ABSTRACT:
According to one embodiment, a first encoder encodes main information, a second encoder encodes sub-information, a first modulator modulates a carrier based on an output of the first encoder, a duplicating module duplicates an output of the second encoder to generate encoded sub-information units, and a second modulator amplitude-modulates an output of the first modulator based on the encoded sub-information units. The second modulator amplitude-modulates with σ/(μ×(2N)1/2) being 0.4 or less, wherein a noise power of a transmission path or a storage medium is σ2, a number of the encoded sub-information units is N, signal levels after amplitude modulation, which correspond to bit1and bit0of the encoded sub-information units, are A and B, and a level difference A−B is μ.
