In order to meet the needs of the optical communication system for the rapid capture of target data and reduce the dynamic tracking error between all levels of communication equipment, a feedforward compensation system for the spatial optical communication system based on embedded technology is designed. With the parallel-to-serial conversion circuit as the only power output device, under the joint adjustment of the three communication equipment components of the optical communication signal transmission module, the wavelength division multiplexing device, and the embedded optical amplifier, the real-time execution capability of the PWM power amplifier is determined to achieve For the scheduling and application of feedforward angle encoders, the construction of feedforward compensation structure for space optical communication systems is realized. Configure the Linux embedded kernel transplantation protocol, create multiple communication data root files under the space light environment, use this as the storage standard, calculate the basic transmission rate of the compensation modulation, realize the modulation and processing of the feedforward pulse wave, and complete the embedding Research on the principle of feedforward compensation in communication systems. The experimental results show that after the feedforward compensation system is applied, when the optical communication parameters are equal to 5.0×1011T, 7.0×1011T, and 9.0×1011T, the target data capture rate exceeds 7.0T/mm, which satisfies the reduction of dynamic tracking between communication devices The actual application requirements of the error.
