    Abstract
  • Buoy wireless communication system can transmit and analyze battlefield environment information in time. But its working environment has limited resources, time-varying characteristics, and so on. Coding based on the principle of separation is not suitable for this complicated situation. This paper analyzes the characteristics of different sources in buoy wireless communication, and proposes two joint source-channel coding methods based on unequal error protection and low density parity check(LDPC) coding for sensor information and image/video information, respectively. Simulation results show that the proposed methods can significantly improve the restorability of important sensor data and image/video information while improving the efficiency of transmission, and ensure the transmission reliability. This study may help to enhance integrated operational capability of Chinese Navy
