提出一种JPEG图像传输的循环码不等差错保护策略,该策略充分考虑JPEG各部分数据重要性的不同,对比较重要的JPEG数据,使用性能较好的差错控制编码对其进行保护;而对重要性一般的JPEG数据,使用性能一般的差错控制编码。在加性高斯白噪声信道中验证该策略,仿真结果表明该策略能保证JPEG图像的稳健传输。 This paper proposes a round robin Unequal Error Protection strategy for JPEG image transmission. This strategy takes full account of the importance of different parts of the JPEG data and protects the more important JPEG data by using the error control code with better performance. The importance of general JPEG data, the use of performance-based error-control coding. The strategy is validated in additive white Gaussian noise channel. The simulation results show that this strategy can guarantee the robust transmission of JPEG images.
