项目摘要
The DFG priority program 1655 (SPP 1655) targets at peak data rates of 100 Gbps and beyond for mobile internet access. In our contribution to SPP 1655, we focus on the indoor scenario with limited mobility, where low-cost low-complexity miniature consumer electronic devices like tablets and smartphones are deployed. In the context of ultra-high data rates for wireless communications, ultra-wideband technology is the most promising technique to achieve the target data rate. When considering only the frequency range from 6-8.5 GHz, where the EIRP mask defined for EU countries has a significant maximum, a spectral efficiency of at least 40 bps/Hz is necessary. In our interdisciplinary (microwave engineering/baseband processing) approach we combine our expertise in the following areas: System architectures enabling extremely high throughput, realization of paradigms for complexity reduction and energy saving of gigabit wireless systems, algorithms for baseband processing in ultra-wideband systems, and investigation of performance parameters of wireless 100 Gbps systems.The key concept introduced in the first phase of SPP 1655 is a multi-mode antenna design in conjunction with advanced baseband processing, dubbed multi-mode massive MIMO. This concept is suitable for miniature devices, as well as for access point arrays. In the first phase, both a user terminal multi-mode antenna with up to five ports based on the rectangular shape of a typical chassis as well as an antenna array with 11x11x4=484 ports suitable for access points has been implemented and characterized. One important outcome is that the feasibility of our system proposal could be proven, both from a microwave engineering as well as from a baseband processing point of view. However, also some bottlenecks could be observed: The limited number of modes that is available over the full ultra-wide bandwidth restricts the number of streams on the uplink and hence limits the data rate.In the second phase, we aim at extensions and optimizations of the proposed concept. This work is motivated by insights obtained during the first phase. Notably, multi-user scenarios will be explored to determine the required hardware to serve a given number of users with a given data rate. Concerning the user terminal, in a joint microwave/baseband optimization approach the possible improvements w.r.t. throughput will be investigated when the restriction that all modes must serve the entire bandwidth is dropped. Particularly, the effect of the additional modes on the channel capacity will be studied. Concerning the access point, a reduction of the size of the antenna elements as well as their spacing is of main concern. For typical channel conditions, this shall enable pre-defined analogue beamforming patterns in order to reduce the processing complexity of the digital beamforming optimization. Furthermore, multi-user multi-stream transmit beamforming will be studied in this context.
DFG优先级程序1655(SPP 1655)针对移动的因特网接入以100 Gbps及以上的峰值数据速率为目标。在我们对SPP 1655的贡献中,我们专注于移动性有限的室内场景,其中部署了平板电脑和智能手机等低成本低复杂度的微型消费电子设备。在无线通信的超高数据速率的背景下,超宽带技术是实现目标数据速率的最有前途的技术。当仅考虑从6-8.5 GHz的频率范围时,其中为欧盟国家定义的EIRP掩码具有显著的最大值,需要至少40 bps/Hz的频谱效率。在我们的跨学科(微波工程/基带处理)的方法,我们联合收割机结合我们在以下领域的专业知识:能够实现极高吞吐量的系统架构,实现用于降低千兆位无线系统的复杂性和节能的范例,用于超宽带系统中的基带处理的算法,SPP 1655第一阶段引入的关键概念是一个多功能的无线通信系统,多模天线设计结合先进的基带处理,被称为多模大规模MIMO。该概念适用于微型设备以及接入点阵列。在第一阶段中,已经实现并表征了基于典型机箱的矩形形状的具有多达五个端口的用户终端多模天线以及具有11 x11 x4 =484个端口的适合于接入点的天线阵列。一个重要的结果是,我们的系统建议的可行性可以证明,无论是从微波工程,以及从基带处理的角度来看。然而,也可以观察到一些瓶颈:在整个超宽带宽上可用的模式数量有限,限制了上行链路上的流的数量,从而限制了数据速率。在第二阶段,我们的目标是扩展和优化所提出的概念。这项工作的动机是在第一阶段获得的见解。值得注意的是,多用户场景将被探索,以确定所需的硬件,以服务于给定数量的用户与给定的数据速率。关于用户终端,在联合微波/基带优化方法中,可能的改进w.r.t.当所有模式必须服务于整个带宽的限制被丢弃时,将研究吞吐量。特别地,将研究附加模式对信道容量的影响。关于接入点,主要关注的是天线元件的尺寸以及它们的间距的减小。对于典型的信道条件,这将启用预定义的模拟波束成形图案,以便降低数字波束成形优化的处理复杂度。此外,多用户多流发射波束成形将在此背景下进行研究。
