parity matrix meaning in English
奇偶矩阵
一致校验矩阵
Examples
- In this paper , we firstly introduce the algorithms of two main approaches that can be utilized to generate ldpc parity matrices with algebraic constructures
本文首先研究了代数结构的ldpc码,详细介绍了两大类,基于有限几何和光正交码字构造的代数结构的ldpc码的数学方法。 - Ldpc ( low density parity check ) code is a kind of linear block code that defined by very sparse parity matrix or tanner graph , and it is also called gallager code since gallager initially presented it
Ldpc ( lowdensityparitycheck )码是一类用非常稀疏的校验矩阵或二分图定义的线性分组纠错码,最初由gallager发现,故亦称gallager码。 - This paper made a careful study on a class of quasi - regular ldpc codes which could encode in linear time only making use of their parity matrix such as - rotation ldpc codes . two factors of the minimum distance and girth length were discussed to improve the performance of these ldpc codes
本文着重研究以旋转ldpc码为代表的准规则结构的ldpc码的构造和编码方法,可以直接利用校验矩阵实现快速线性编码,并从码距和围长两个方面,对这类ldpc码字性能进行分析和优化。 - In next mobile communication system to suffice more and more high - speed data service and demand of qos ( quality of service ) many new wireless link layer transport technologies are going to be used such as mimo ( multiple input multiple output ) , ofdm ( orthogonal frequency division multiplexing ) , channel coding and acm ( adaptive coding modulation ) etc . low density parity check ( ldpc ) codes were first discovered in 1960 ’ s which belong to linear block codes with their parity matrix being sparse
下一代移动通信系统为了满足移动用户对高速、宽带数据传输业务不断增长和更高服务质量的要求,采用了许多新的无线链路传输技术,包括多天线发射和接收技术、正交频分复用技术、信道纠错编码技术和自适应编码调制技术等。上世纪60年代提出的低密度校验码,是一种校验矩阵为稀疏矩阵的线性分组码。
