Problems solved by technology

[0004] In the existing GFDM system, there is a filter in the transmission channel to filter the information of each symbol in the codeword vector. The filtering causes interference between the information of each symbol in the transmitted information, and the interference between the information of the symbols is expressed in the frequency domain Inter-carrier interference, which makes the performance of GFDM system information transmission lower

Abstract

The embodiment of the invention provides an information transmission method and device, an electronic device and a storage medium. The information transmission method comprises the steps of determining at least a polarization code transmission channel of a GFDM (Generalized Frequency Division Multiplexing) system based on a two-step channel polarization transformation method; determining reliability of each polarization transmission channel; obtaining a to-be-transmitted information vector, coding the information vector through a coding method and modulating the coded information vector through a preset signal modulation method to obtain the sent information vector; selecting a target polarization code transmission channel which has the byte number as same as that of the sent information vector and has high reliability from the at least one polarization code transmission channel; and transmitting the sent information vector to a receiving end through the target polarization code transmission channel. According to the embodiment of the invention, the information transmission method which combines the polarization code and the GFDM system can improve the information transmission performance of the GFDM system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an information transmission method, device, electronic equipment and storage medium. Background technique [0002] GFDM (Generalized Frequency Division Multiplexing, Generalized Frequency Division Multiplexing) system is a flexible non-orthogonal multi-carrier system. It performs carrier modulation based on time-frequency two-dimensional data block structure, can flexibly configure system parameters to meet the needs of different application scenarios, and can effectively reduce system out-of-band power leakage. It is one of the important supporting technologies for future mobile communication systems. [0003] In the actual digital communication process, it is necessary to encode the channel for transmitting information to improve the security and reliability of transmitting information. The channel coding method in the existing GFDM system is Turbo coding. The s...
