项目摘要
Today there exist over 20 billion devices connected to the internet. In the coming three years, the number will increase by 10 billion more devices. The share of wireless communication is significantly increasing and rises an interesting and economic important challenge for the cellular mobile networks to support terminals with increasing data rates with limited resources in interference-limited environments. Multiple antenna systems, so called multiple-input multiple-output (MIMO) systems increase the spectral efficiency, allow spatial multiplexing, and decrease the outage probability by diversity. Furthermore, new technologies such as non-orthogonal multiple-access (NOMA) and caching of data at certain nodes in the network allow to improve the spectral efficiency and throughput further. By the MIMO prototyping system the two lowest layers of the protocol stack, the physical and the medium access control layer can be easily changed and novel algorithms for resource allocation, power control and spatial and spectral precoding can be adapted. Even complex multi-cell scenarios with distributed transmit and receive nodes can be illustrated and evaluated. The MIMO prototyping system allows the Institute of Communications Technology to proceed with the whole development process from algorithm analysis and development for resource allocation and assignment to the implementation and assessment on the prototype system. The MIMO prototyping system will be applied for the following research areas: multi-user beam forming concepts for the downlink, cooperative multipoint techniques for downlink, metrological verification and validation of wireless finger prints and distributions, verification of symmetrizability of arbitrary varying channels. Finally, we expect from the experiences and results of the implementations on the MIMO prototyping system to develop novel theoretical approaches and questions, which then are implemented and tested on the system.
今天,有超过200亿台设备连接到互联网。在未来三年内,这一数字将增加100多亿台。无线通信的份额正在显著增加,这对蜂窝移动网络在干扰有限的环境中以有限的资源支持数据速率不断增加的终端提出了一个有趣且经济的重要挑战。多天线系统,即多输入多输出(MIMO)系统,提高了频谱效率,允许空间复用,并通过分集降低了中断概率。此外,诸如非正交多址(NOMA)和网络中某些节点的数据缓存等新技术允许进一步提高频谱效率和吞吐量。通过MIMO原型系统,可以很容易地改变协议栈的最低两层,物理层和介质访问控制层,并且可以适应新的资源分配,功率控制以及空间和频谱预编码算法。甚至具有分布式发送和接收节点的复杂多单元场景也可以进行说明和评估。MIMO原型系统允许通信技术研究所进行整个开发过程,从算法分析和开发资源分配和分配到原型系统的实施和评估。MIMO原型系统将应用于以下研究领域:下行链路的多用户波束形成概念、下行链路的协同多点技术、无线指纹和分布的计量验证和验证、任意变化信道的对称性验证。最后,我们期望从MIMO原型系统实现的经验和结果中发展出新的理论方法和问题,然后在系统上实现和测试。
