Abstract: Techniques are disclosed relating to LDPC encoding. In some embodiments, a set of operations is produced that is usable to generate an encoded message based on an input message. In some embodiments, the set of operations correspond to operations for entries in a smaller matrix representation that specifies locations of non-zero entries in an LDPC encoding matrix. In some embodiments, a mobile device is configured with the set of operations to perform LDPC encoding. Circuitry configured with the set of operations may perform LDPC encoding with high performance, relatively small area and/or low power consumption, in some embodiments.

Abstract translation: 公开了与LDPC编码相关的技术。 在一些实施例中，产生一组可用于基于输入消息生成编码消息的操作。 在一些实施例中，该组操作对应于在LDPC编码矩阵中指定非零条目的位置的较小矩阵表示中的条目的操作。 在一些实施例中，移动设备配置有用于执行LDPC编码的一组操作。 在一些实施例中，配置有该组操作的电路可以执行具有高性能，相对小的面积和/或低功耗的LDPC编码。
