本文提出了三种用于构建Q- ARY LDPC代码的代数方法。第一种方法将一类分散的芦苇固体代码作为LDPC代码。第二种方法给出了一类Q-ARY准环LDPC代码。第三种方法给出了两类Q-ARY有限几何形状LDPC代码。这些方法构建的代码在迭代解码方面的性能非常好,即使对于简短的代码也是如此。
This paper presents three algebraic methods for constructing q-ary LDPC codes. The first method gives a class of dispersed Reed-Solomon codes as LDPC codes. The second method gives a class of q-ary quasi-cyclic LDPC codes. The third method gives two classes of q-ary finite geometry LDPC codes. Codes constructed by these methods perform very well with iterative decoding, even for short codes.
