多低密度奇偶校验检查（LDPC）基图设计
摘要：
本公开内容的方面涉及利用LDPC基图的低密度奇偶校验检查(LDPC)编码。可以维护与重叠的信息块长度的不同的范围相关联的两个或更多个LDPC基图。可以针对信息块基于所述信息块的信息块长度选择具体的LDPC基图。在选择所述LDPC基图时可以被考虑的额外的度量可以包括被用于对所述信息块进行编码的码率和/或为了产生所述信息块的所述信息块长度而被应用于每个LDPC基图的提升大小。
摘要（英）：

Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing LDPC base graphs. Two or more LDPC base graphs may be maintained that are associated with different ranges of overlapping information block lengths. A particular LDPC base graph may be selected for an information block based on the information block length of the information block. Additional metrics that may be considered when selecting the LDPC base graph may include the code rate utilized to encode the information block and/or the lift size applied to each LDPC base graph to produce the information block length of the information block.
