摘　　要：介绍在物联网传输信道中喷泉码的校验矩阵的生成办法,以此平衡收发双方的通信代价.然后使用两种熵编码压缩算法对校验矩阵进行压缩,从而降低由于校验矩阵规模增大而带来的过高传输代价.实验结果表明,对校验矩阵的压缩,确实能够降低传输代价,同时针对不同信道,使用熵编码压缩的效果较好.The generation methods of the testing matrix of fountain codes in the channel of internet of things are introduced in order to balance the communication cost between the sender nodes and receiver nodes. Two compression algorithms of entropy coding were used to compress the testing matrix so as to decrease the cost when the scale of the testing matrix becomes larger. The result showed that the cost can be reduced consequently when the testing matrix is compressed, meanwhile the good effect is acquired when the entropy codes are compressed for the different channels.
