| Abstract: | At present, data from many ocean monitoring platforms is transmitted by satellite. There is a noticeable expensive question in satellite communication, though it has many advantages. Based on the characteristics of ocean monitoring data transmitted by satellite, the application of Huffman data compression can improve the satellite communication efficiency and reduce the communication expenses. The paper mainly introduces the theory of Huffman data compression and how to apply its technique to satellite data communication of ocean monitoring platforms. |
