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.

新的报告显示，许可的无线系统在带宽方面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，这需要更好地利用带宽。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，在频谱中“填充间隙”，即，使用未被充分利用的频带。认知系统将在未来的通信中扮演越来越重要的角色，对认知网络的研究也在不断发展，一方面要设计出实用的认知网络传输策略，另一方面要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。我们的目标是调查给定的网络的能力和自由度，使用信息论和信号处理的工具。在这个过程中，它旨在开发传输策略（编码/解码）和干扰管理的方法，并比较不同的认知可能性。
