奇偶矩阵 meaning in Chinese

parity matrix

The ldpc code ’ s parity check matrix generated by this scheme has high girth and can be used to coding directly , the coding complexity is lower . as to the decoding algorithm , i modify the message passing algorithm based on the girth that i can get in the structure of parity check matrix to improve the decoding performance . what is more , the new structure of the parity check matrix is easy to implement with the hardware
接着着重围绕ldpc码的校验矩阵构造方法和译码算法展开讨论,在比特填充算法的基础上提出了一种ldpc码联合编译码方案,通过该方案构造的校验矩阵不仅具有良好的girth分布,而且能直接用于编码,编码的计算复杂度低;在译码方面,利用构造奇偶矩阵过程中girth分布信息,优化解码迭代过程,能有效提高系统性能;并且该方案构造的校验矩阵更易于实际的编译码硬件实现。
