CICERO- Cognitive bi-directional relay interference network: Fundamental performance limits

新的报告显示，获得许可的无线系统在带宽方面并没有充分利用网络资源。另一方面，对更高数据速率的需求正在增加，这就要求更好地利用带宽。提高通信网络效率的一种可能性是使用认知无线电。认知无线电是干扰网络中的一个新兴领域，其技术有望在频谱效率方面提高网络性能。它可以更好地利用带宽，例如，通过“填补频谱中的空白”，即使用未充分利用的频带。预计认知系统将在未来的通信中发挥更重要的作用。认知网络的研究是一个不断发展的过程，一方面旨在为认知网络设计实用的传输策略，另一方面推导出认知网络性能的理论极限。在这个项目中，我们的目标是研究认知在双向中继干扰网络中的影响。我们的目标是利用信息理论和信号处理工具来研究给定网络的容量和自由度。在此过程中，旨在制定传输策略（编码/解码）和其中的干扰管理方法，并比较不同的认知可能性。

New reports show that licensed wireless systems do not fully exploit network resources in terms of bandwidth. On the other hand, the demand for higher data rates is increasing, which requires better exploitation of bandwidth. One possibility to increase the efficiency of communication networks is the use of cognitive radio. Cognitive radio is an emerging field in interference networks, whose techniques promise improved network performance in terms of spectral efficiency. It makes better use of bandwidth by, e.g., “filling gaps” in the spectrum, i.e., using frequency bands that are not fully exploited. It is anticipated that cognitive systems will play a more important role in the future of communications.The study of cognitive networks is an ongoing process these days, aiming at designing practical transmit strategies for cognitive networks on the one hand, and deriving theoretical limits of performance of such networks on the other hand. In this project, our objective is to study the impact of cognition in bi-directional relay interference networks. We aim to investigate the given network in terms of capacity and degrees of freedom using tools from information theory and signal processing. In this process, it is intended to develop transmit strategies (coding/decoding) and methods of interference management therein, and compare different cognition possibilities.
