Disclosed are a frequency offset estimation method and apparatus in an optical transmission network and a storage medium. The method comprises: acquiring a data symbol to be frequency offset estimated, and eliminating a noise phase, a phase generated by a light source and an information phase in the data symbol to be frequency offset estimated; and performing a correlation operation on a data symbol with a set interval in the data symbol after the elimination processing and using a correlation operation result to determine a frequency offset estimation value.

Frequency offset estimation method and apparatus in optical transmission network and storage medium

The disclosure discloses a transmission method and a transmission apparatus based on point-to-point wireless communication. The method includes that: a state machine of a sending-receiving terminal performs state transition according to a received training frame; and when the state machine of the sending-receiving terminal is transferred to a data frame sending state, user data is sent. According to the disclosure, the sending-receiving terminal sends a preset training frame in a synchronous linking process so as to promote the rapid linking of two peer nodes; the saved linking time is spent to send data so as to increase the throughput of the user data; due to the state transition of the state machine, a receiver can determine the arrival time of a data frame, thereby improving the stability and the reliability of the system; and moreover, the training of the training frame can ensure that a receiver decodes a first data frame successfully, so that the flow of judging whether the received data is the user data by the receiver is simplified and the efficiency is improved.
