Problems solved by technology

[0007] For each OFDM subcarrier, the signal-to-noise ratio information of each OFDM subcarrier is different. In the prior art, fixed signal-to-noise ratio information is used to polarize the information to be transmitted, resulting in poor reliability of the polarized channel. inaccurate, thereby degrading the performance of transmitting polar codes in each OFDM subcarrier

Abstract

The embodiment of the present invention provides an information transmission method, system, device, and electronic equipment, including: obtaining the signal-to-noise ratio information of each OFDM subcarrier, and based on the signal-to-noise ratio information of each OFDM subcarrier, according to the polar code encoding rule , encode the information to be transmitted, obtain the polar code, and convert the polar code into the OFDM signal to be transmitted, and transmit the OFDM signal to be transmitted, because the neural network model completed in advance can obtain the signal-to-noise of each OFDM subcarrier in real time Ratio information, so that the signal-to-noise ratio information transmitted by each OFDM sub-carrier can be sent to the sender, so that the sender can perform polarization coding on the transmission information according to the signal-to-noise ratio information of each OFDM sub-carrier transmission determined in real time, which can be better The polarized channel communication is selected according to the reliability of the polarized channel, and the performance of polarized code transmission in each OFDM subcarrier is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, system, device and electronic equipment. Background technique [0002] With the continuous development of Internet technology, increasing the data transmission rate has become a major demand for optical fiber communication technology. OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) is one of MCM (Multi Carrier Modulation, multi-carrier modulation) technologies. Because of its low implementation complexity, strong anti-multipath attenuation performance, high frequency band utilization and many other advantages, it is widely used in optical communication systems. [0003] On the other hand, as a channel coding method that has been strictly proven to achieve channel capacity, polar codes have gradually been used in the field of communication. Therefore, a method combining polar codes an...
