    摘要： The transmitter includes a first bit generator, a modulator, a second bit generator and a bit converter. The first bit generator generates bits to be transmitted based on the first wireless scheme. The modulator for the first wireless scheme performs at least amplitude modulation of a multiple level on the bits generated by the first bit generator. The second bit generator generates a bit to be transmitted based on the second wireless scheme. The bit converter converts the bit generated by the second bit generator and inputs converted bits to the modulator wherein the bit converter converts the bit generated by the second bit generator so that a signal showing High in the second wireless scheme is modulated to amplitude of a high level in the multiple level in the modulator.
