论文摘要
提出了两连锁案例二进制首席执行官（CEO）问题的联合与连续的解码方案之间的比较。我们利用对数损失作为测量和比较解码技术的总失真的标准。二元对称通道（BSC）被认为是测试通道模型，该模型提供了理论速率延伸。仿真结果表明，与连续的解码方案相比，关节解码方案提供了较小的压缩率和失真值。另一方面，连续的解码方法的复杂性较低。因此，对于链接次数较高的情况是有效的。
A comparison between the joint and the successive decoding schemes for a two-link case binary Chief Executive Officer (CEO) problem is presented. We utilize the logarithmic loss as the criterion for measuring and comparing the total distortion of the decoding techniques. The binary symmetric channel (BSC) is considered as the test-channel model, which provides a theoretical rate-distortion bound. Simulation results show that the joint decoding scheme provides smaller compression rate and distortion values compared to the successive decoding scheme. On the other hand the successive decoding method has lower complexity; therefore, it is efficient for the cases with higher number of links.
