摘要

低密度奇偶校验(LDPC)码是目前已知的最好的信道码之一，目前和未来的通信标准正在讨论中。利用坦纳图可以有效地对LDPC码进行建模。在本文中，我们提出了这种图形的一种新的硬件高效的2向量设计方法。我们展示了用这种方法创建的示例代码的通信性能结果，以及适用于混合arq的灵活的多速率2V-LDPC解码器和编码器的相应实现结果

Design of irregular LDPC Codes for flexible Encoder and Decoder Hardware Realization

Low-density parity-check (LDPC) codes are among the best channel codes known today and are in discussion for current and future communications standards. LDPC codes can be efficiently modeled by Tanner-graphs. In this paper, we present a novel hardware-efficient 2-vector design method of such graphs. We show communications performance results for an exemplary code created by this approach and corresponding implementation results for a flexible, multi-rate 2V-LDPC decoder and encoder applicable for hybrid-ARQ
