摘 要:该文用一种级联码模型描述了LDPC 编码高阶调制系统。该级联码模型以LDPC 码为外码,二-十进制转换码为内码,再加一个删余模块构成。基于这种级联码模型,该文给出了其联合校验方程和二分图,并提出了级联码置信度传播算法,实现了LDPC...
摘 要:该文在研究缩减伴随式集译码(RLSD)算法和规则QC-LDPC 码字结构的基础上,提出了一种新的针对中短QC-LDPC 码的BP-RLSD 级联译码算法。BP 算法译码失败时的软输出对数信息,作为RLSD 算法的输入。根据QC-LD...
摘 要:对于围长(girth)至少为8的低密度奇偶校验(LDPC)码,目前的绝大多数构造方法都需要借助于计算机搜索。受贪婪构造算法启发,该文利用完全确定的方式构造出一类围长为8的 (3,L)−规则QC-LDPC码。这类QC-LDPC码的校验...
pic cpu source code. it is writed in the verilog source code. it can work on the 40Mhz high speed.
vhdl code for ALU.i think by reading his code..it will be very easy for you to design an Alu.
