查询词典 parity check

In this advanced architecture of QC-LDPC codes encoder, the RAM is advisably used to store the parity-check bits and the pointers are introduced as the addresses of the RAM instead of shift registers used for storing the generator of H. Thus, the encoding; process can be achieved by reading and writing on RAM and the parity-cheek bits can be output serially.

采用RAM存储校验位，并引入指针来指示RAM的地址方法，从而取代传统编码架构中的移位寄存器，使编码过程通过对RAM的读写操作实现，校验位序列也通过对RAM的读操作串行输出。
