项目摘要

We gave an explicit evaluation of the interval algorithm for random number generation based on the number system. Using this expression we obtain an improved bound on the performance analysis of the interval algorithm. We formulate a new scheme of random number generation using the framework of multiterminal source coding system and gave the solution to it. Consider the situation where many distributed sensors observe noisy versions of an emitted signal. Those noisy data are separately encoded and sent to one information center, where the CEO(Chief Executive Officer) wishes to reconstruct the signal. In this communication system the problem to determine the trade-off between the estimation error and transmission rates is called the CEO problem. In 1998, the head investigator solved the Gaussian CEO problem, where the emitted signal is Gaussian and the observed signals are noisy version of the signal corrupted by independent additive white Gaussian noises. In 2005 we extended the result … More of Gaussian CEO problem. We have further extended the result we obtain in 2005. We have also extended the Gaussian CEO problem to the case where the emitted signal and additive noises are Gaussian random vector and have obtained partial solution to this problem. We have considered the discrete CEO problem and have derived upper and lower bounds of the optimal transmission rate. We have discussed the close relation between sensor networks and multiterminal information theory, demonstrating that our obtained results play important roles in the construction of theory of sensor networks. We consider a relay channel where a relay helps the transmission of messages from one sender to one receiver. The relay is considered not only as a sender that helps the message transmission but as a wire-tapper who can obtain some knowledge about the transmitted messages. In 2001 the head investigator studied the coding problem of the relay channel under the situation that some of transmitted messages are confidential to the relay. He gave a partial solution to this problem. We considered the problem again and gave the complete solution for a class of relay channels. Less

我们根据数字系统对随机数生成的间隔算法进行了明确的评估。使用此表达式，我们获得了对间隔算法的性能分析的改进结合。我们使用多性源编码系统的框架制定了一个新的随机数生成方案，并为其提供了解决方案。考虑许多分布式传感器观察发射信号的噪声版本的情况。这些噪声数据分别编码并发送到一个信息中心，首席执行官（首席执行官）希望重建信号。在此通信系统中，确定估计误差和传输速率之间的权衡的问题称为首席执行官问题。 1998年，首席调查员解决了高斯首席执行官问题，其中发射信号为高斯，观察到的信号是由独立的附加性白色高斯噪音损坏的信号的噪声版本。 2005年，我们扩展了结果……更多的高斯首席执行官问题。我们进一步扩展了2005年获得的结果。我们还将高斯首席执行官问题扩展到了发射信号和添加的噪声为高斯随机矢量并为此问题提供了部分解决方案的情况。我们考虑了离散的CEO问题，并衍生了最佳传输速率的上限和下限。我们已经讨论了传感器网络与多性信息理论之间的密切关系，表明我们获得的结果在传感器网络理论的构建中起着重要作用。我们考虑一个继电器通道，其中继电器有助于将消息从一个发件人传输到一个接收器。继电器不仅被视为有助于消息传输的发件人，而且还被视为可以获得有关传输消息知识的电汇者。在2001年，调查员在某些传输消息对继电器充满信心的情况下研究了继电器渠道的编码问题。他为这个问题提供了部分解决方案。我们再次考虑了这个问题，并为一类中继渠道提供了完整的解决方案。较少的
