摘　　要：介绍自适应多边类型低密度奇偶校验码(MET-LDPC)多码率编码方案,在不改变编码器生成矩阵的基础上采用规则删余的方法构造多码率编码并硬件实现。在编码器硬件实现中,采用寄存器组比特交织方案,减少资源占用,提高了处理能力。在占用较低硬件资源的情况下,编码器吞吐量为100Mbit/s,满足高速编码的要求。The adaptive encoding scheme of MET-LDPC is proposed that can encode information bits in any code rate without amending generated matrix by rule puncturing. Meanwhile, in the process of encoder＇s implementation, a new bit interleaved scheme adopted, which can reduce resources occupation and improve the work efficiency. The encoder＇s throughput is 100 Mbit/s with little hardware device and meets the demand of high speed encoding application.
