MODULATOR, MODULATION SYSTEM, AND METHOD FOR IMPLEMENTING HIGHER ORDER MODULATION

摘要

Embodiments of the present disclosure disclose a modulator, including: a first modulation module, configured to: receive first to-be-modulated data, and output a first transmission curve according to the first to-be-modulated data; a second modulation module, configured to: receive second to-be-modulated data, and output a second transmission curve according to the second to-be-modulated data, where a period of the second transmission curve is half of a period of the first transmission curve; and a combination module, configured to perform phase superposition on the first transmission curve and the second transmission curve, to obtain a combined linear result. In addition, this solution further provides a modulation system and a method for implementing higher order modulation, so that a linear result that can be modulated can be obtained by controlling a superposition ratio between transmission curves, to implement linear curve transmission.
