<p>Disclosed are an electro-optic modulation device, method, transmitter, and system, relating to the field of communications. Pre-distortion compensation is performed on a digital electrical signal through a non-linearity memory polynomial so as to eliminate the non-linearity of an electro-optic modulation device with high accuracy, high production efficiency, a simple structure, easy implementation, and low costs. The electro-optic modulation device comprises: a receiving unit, a compensation unit, and an electro-optic modulator which are connected successively, wherein the receiving unit is used for receiving a digital electrical signal u (n); the compensation unit is used for performing pre-distortion compensation on the digital electrical signal u (n) according to said non-linearity memory polynomial so as to acquire a digital electrical signal x (n) after pre-distortion compensation is performed thereon; and the electro-optic modulator is used for converting the digital electrical signal x (n) after pre-distortion compensation is performed thereon into an optical signal.</p> |
