The proposed research will investigate into cooperative communications and networking (i) to coordinate a cluster of base stations to provide multi-cell cooperation so as to expand the capacity of a single isolated cell and mitigate inter-cell interference in wireless cellular networks, (ii) to enhance signal reception at the destination receiver through cooperative relaying and diversity transmission/reception, while ensuring secure communication by introducing techniques to mitigate intentional and unintentional adversaries, e.g., malicious nodes and eavesdroppers, and (iii) to effect cooperative spectrum access in cognitive radio networks to achieve spectrum and energy efficiencies while satisfying the requirements of licensed or primary users (PUs). The fundamental reason for a source (sender) to engage a third party as partner(s) to relay its signal is because the quality of the direct link from source to destination may be very poor, e.g., either blocked by obstacles in the direct path or faded by impairments inherent in the wireless channel.

拟议的研究将探讨协作通信和网络：(I)协调基站集群以提供多小区协作，以扩展单个孤立小区的容量并缓解无线蜂窝网络中的小区间干扰；(Ii)通过协作中继和分集发送/接收来增强目标接收器的信号接收，同时通过引入技术来确保安全通信，以减少有意和无意的对手，例如恶意节点和窃听者；以及(Iii)在认知无线电网络中实现协作频谱接入，以在满足许可或主用户(PU)的要求的同时实现频谱和能量效率。源(发送方)将第三方作为合作伙伴(S)来转播其信号的基本原因是，从源到目的地的直接链路的质量可能非常差，例如，被直接路径中的障碍物阻塞或被无线信道中固有的损害所干扰。
