The embodiments of the invention disclose a communication device, method and system, an electronic device and a computer readable storage medium. The communication device comprises a sending device and a receiving device. The sending device comprises a time-frequency reference device, a framing device, an encoder, a modulator and a codirectional receiver. The codirectional receiver is connected tothe modulator and is used for carrying out codirectional receiving and processing on a sending information frame to acquire codirectional recovery frame synchronization information. The receiving device comprises a heterodromous receiver and is used for carrying out heterodromous receiving and processing on an information frame received from a communicated opposite terminal. Under conditions thatexisting communication channel resources are shared and data is transmitted at the same time, delay jitter caused by link asymmetry in bidirectional time comparison can be eliminated and high-precision time comparison is realized. The integrated design of communication and time comparison is realized so that channel resources are saved and system integration benefits are increased.
Description
technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a communication device, method, system, electronic equipment, and computer-readable storage medium. Background technique [0002] High-precision time synchronization technology has important application value in high-tech application fields such as communication, time measurement, deep space exploration, and national defense. Time comparison is the premise and basis for high-precision time synchronization. To achieve high-precision time synchronization, high-precision time comparison must be achieved first. As a high-precision time comparison method, two-way time comparison is the key direction of communication technology and time comparison technology research. [0003] The basic principle of the two-way time comparison method is that two nodes send and receive time synchronization data to each other through a two-way link. The approximate sym...
