Traditional mobile/wireless systems that use single-antennas terminals (ie handsets and base-stations etc) cannot keep up with the user demand for increased data rates. Consequently, multiple-input multiple-output (MIMO) or "multiple-antenna technology" has been developed, which achieves higher data rates and better link reliability than conventional single-antenna systems. It has already been deployed in the third generation broadband wireless networks, wireless local area networks (802.11n) and will also be an integral technology for fourth generation networks (e.g. long-term evolution (LTE)). However, small phone handsets cannot support multiple-antennas owing to constraints on physical size, batterypower. This constraint has led to the idea of cooperative relay networks. The promise of cooperative relaying has already led to evolving standards (e.g. IEEE 802.16j). Such relaying can be further extended to multiple-antenna relay networks. This approach is feasible for most broadband terminals, wireless laptops and broadband wireless switches, for instance, that can accommodate multiple antennas. This project will focus more on communication technologies for multiple-antenna two-way relaying systems. For instance, channel and frequency estimation methods, signaling methods, and practical coding and decoding techniques will be developed. The MIMO two-way relay technology is the solution for the next generation energy, bandwidth efficient wireless networks. The proposed research thus aims to develop related MIMO, OFDM, CR and relay technologies, contributing to the advancement of 4G wireless standards such as IMT-A.

使用单天线终端（即手机和 基站等）不能跟上用户对增加的数据速率的需求。因此，多输入 已经开发了多输出（MIMO）或“多天线技术”，其实现更高的数据传输速率。 速率和更好的链路可靠性比传统的单天线系统。它已经部署在第三代宽带无线网络，无线局域网（802.11n），也将是一个 第四代网络（例如长期演进（LTE））的集成技术。 然而，小型手机由于物理尺寸、电池电量等方面的限制，无法支持多天线。这种限制导致了协作中继网络的想法。协作中继的前景已经导致了演进的标准（例如IEEE 802.16j）。这种中继可以进一步扩展到多天线中继网络。这种方法对于大多数宽带终端、无线笔记本电脑和 例如，可以容纳多个天线的宽带无线交换机。 这 该项目将更多地侧重于多天线双向中继系统的通信技术。为 实例，信道和频率估计方法，信令方法，和实际 将开发编码和解码技术。 MIMO双向中继技术是下一代能量、带宽高效的无线网络的解决方案。因此，拟议的研究旨在开发相关的MIMO，OFDM，CR和中继技术，为IMT-A等4G无线标准的进步做出贡献。
