Description: 该程序描述的是数字电视地面广播中卷积交织部分.因为是卷积交织所以最后结果中出现为的数值表示该值是前一包缓冲数据的数.但针对第一包数据做卷积交织时,这些零位置上最后确实自动补零.-The procedure is described in digital TV terrestrial broadcasting in parts of Convolutional Interleaver. Convolutional Interleaver because it is so final results for the numerical value is that the previous data on the number of packet buffer. But for the first packet data do Convolutional Interleaver These zero position is indeed the last automatic zero. Platform: |

Description: 交织可以使信道的突发错误转化成随机错误，是通信过程中的一个非常重要环节。实际应用中，交织类型非常之多，但最典型的类型主要有矩阵交织、卷积交织，和存储器交织，深刻了解交织原理的最好方式是对其仿真算法的实现，本算法来自卫星通信一线技术人员，非常精炼，值得通信同行借鉴。(Interleaving can make the burst error of the channel be transformed into random error, and it is a very important step in the communication process. In practical application,too many interleaving types are exist, but the most typical types are matrix interleaver, convolutional interleaver, and ram interleaver, the best way of understanding interleaver is to realize it with simulation algorithm, this algorithm is very refined, worthy of reference for communication.)
