Abstract

The invention discloses a multiuser coding multiplexing method. The multiuser coding multiplexing method comprises the following steps: respectively receiving multiple paths of input data by using multiple memories; determining a read memory according to a buffer instruction; and encoding the input data in the read memory, and allocating an encoding mark for the read memory. Meanwhile, the invention further discloses a coding multiplexing device and a state control method for the coding and multiplexing device. The multiuser coding multiplexing method disclosed by the invention is used for realizing the multiuser multiplexing of LDPC encoding.

Description

technical field [0001] The invention belongs to the technical field of encoding, and in particular relates to an encoding multiplexing method and device which can be used by multiple users. Background technique [0002] LDPC code is Low Density Parity Check Code (LowDensityParityCheckCode, LDPC), which was proposed by Dr. RobertG. With low complexity and flexible structure, it is a research hotspot in the field of channel coding in recent years. It has been widely used in deep space communication, optical fiber communication, satellite digital video and audio broadcasting and other fields. [0003] The inventor was engaged in research on LDPC codes and found that the original data generated for multiple users is limited by the resources of the encoding device, and the encoding of multi-user data cannot be realized in time. Therefore, it is necessary to propose an LDPC code encoding applicable to multiple users. multiplexing technology. Contents of the invention [0004] ...
