Abstract

The invention provides a method and device for processing LDPC encoding. The method comprises the steps of determining the number of RAMs according to the number of lines of a mother matrix of LDPC, sequentially writing information bits input every time and data bits read from RAM units of the RAMs corresponding to each line of the mother matrix every time into the RAM units of the RAMs corresponding to each line into the RAM units of the RAMs corresponding to each line in an iteration mode according to the value of information bits in each line of the mother matrix, and the step of outputting the data bits stored in the RAM units of the RAMs corresponding to each line until the last information bit of each line. By means of the method and device for processing the LDPC encoding, the problems that LDPC encoding in the prior art is low in encoding efficiency and narrow in applicable occasions, a corresponding encoder structure is complex and resources are wasted are solved, and the purposes that delay is small, the structure is simple, the handling capacity is large, and the generality is good are achieved.

Description

technical field [0001] The present invention relates to the field of communications, in particular, to a low-density parity-check code LDPC encoding processing method and device. Background technique [0002] Microwave communication, optical fiber communication and satellite communication are called the three main means of modern communication transmission. Microwave communication generally adopts a point-to-point transmission mode, and is currently mainly used in 2G / 3G mobile bearer networks to provide voice and data service transmission for mobile operators. It has large transmission capacity, stable long-distance transmission quality, low investment, and short construction period. Features such as easy maintenance. The coding scheme in microwave communication is realized by Low Density Parity Check Code (LDPC for short) coding. [0003] The original LDPC code encoding algorithm is the same as ordinary block codes. First, the check matrix is ​​converted into a generator ...
