Research on LDPC codes in 5G standards and applications in image transmission system
In the fifth generation mobile communication system(5G),Low-Density Parity-Check(LDPC)codes are used as the channel coding scheme for the data channel in enhanced mobile broadband application scenarios in order to satisfy the user's need to access the network anytime and anywhere.In this paper,we discuss the application of LDPC code in 5G standard in image transmission,and the simulation results show that compared with the image transmission system without channel compiled code,the system encoded by LDPC code has a very obvious improvement of image quality under the same conditions of signal-to-noise ratio,and it is already very close to the original image when the signal-to-noise ratio is 2 Db.
