Embodiment Construction

[0056] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described The embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0057] In the hardware circuit implementation process, the existing public methods are basically aimed at binary LDPC, and the code word verification implementation method for 64-ary LDPC has not yet been seen. Therefore, the application provides a The code word verification method of the 64-ary LDPC is described by taking the 64-ary (48, 96)...

Abstract

The invention discloses a codeword verification method of a 64-system LDPC. The method comprises the following steps: respectively storing positions and values of non-zero elements of a verification matrix; acquiring a codeword decision value corresponding to a non-zero element according to the position of the non-zero element of the check matrix; calculating and obtaining a check result accordingto the codeword decision value and the value of the non-zero element; judging whether the verification results are all 0 or not; if the verification results are all 0, indicating that the verification is successful; and if the verification results are not 0, indicating that the verification fails. According to the codeword verification method of the 64-system LDPC, provided by the invention, thepositions and the values of the non-zero elements of the 64-system verification matrix are separately and independently stored; calculation of all elements is represented by calculation of non-zero elements, and only one row of a check matrix is checked in each check, so that the operand is greatly reduced, the operation complexity is reduced, less logic resources are consumed, and code word checkof the hexadecimal LDPC is realized.

Description

technical field [0001] The present application relates to the technical fields of electronic circuits and semiconductors, in particular to a method and system for verifying codewords of 64-ary LDPC. Background technique [0002] Channel coding technology is an indispensable key technology for mobile communication systems, and LDPC (Low Density Parity Check, Low Density Parity Check) code in channel coding technology is generally considered to be a channel coding method with superior performance. It has attracted widespread attention for its performance approaching Shannon's limit, and has been applied in the research of the fourth generation mobile communication system. [0003] LDPC code is a relatively special linear block code. The particularity lies in the fact that the number of 1s in its parity check matrix is ​​far less than the number of 0s. It is called sparse type, also known as low density, and uses an iterative decoding algorithm. The performance of the LDPC cod...
