Proposal Summary - Novel Beam Steering Apertures and Waveforms for High Capacity Broadband Wireless Nodes Intellectual MeritThe demand for broadband wireless has put existing systems to their limits. In not so distant future mobile Gb/s portable and wearable wireless nodes will be required which will necessitate significant improvements in spectral efficiency. This work proposes an integrated research concept which brings together innovations in beam steering antenna arrays and interference immune waveforms and algorithms. To date most of the antennas and arrays that have been developed for portable and wearable wireless applications have fixed broad beams. This makes them very inefficient because much of the radiated radio frequency power is absorbed by the head or the body resulting in wasted battery power. In this work led by USC significantly smaller form factor antenna arrays will be developed by exploiting the steerable parasitic array concept. The dependency of the array gain and angular coverage on array parameters will be studied to develop new design rules. From a systems perspective, efforts have been devoted to maximize spectral efficiency within heterogeneous networking strategies. However, conventional spectrum utilization strategies which are developed for homogeneous networks are being integrated to the heterogeneous networks, which stand as the bottleneck of the heterogeneous network. To break that bottleneck the concept of enhanced partial overlapping domains is proposed by the USF team. For the first time, beam steering approaches at the mobile will be combined with time-frequency utilization considering enhanced partially overlapped domains. A system level testbed will be developed to evaluate the performance of the proposed arrays and waveforms. Broader ImpactsThe broader impact of this work includes its potential for new fundamental knowledge generation in the field of beam steering antenna arrays and interference immune waveforms/algorithms for future high capacity portable/wearable wireless applications. This will have effects on commercial and military communication domains. Immediate tangible outcome will be a system level testbed that will provide results, outcomes, and design guidelines to prospective designers. This research also involves a team from Benedict College, Columbia, SC, an HBCU (Historically Black Colleges and Universities) Institution. The Benedict team will conduct research and educational activities that will lead to the development of demonstration modules that will enhance future outreach and recruitment efforts of undergraduate students, high school students, and female and minority studen

建议摘要-用于高容量宽带无线节点的新型波束控制结构和波形知识产权对宽带无线的需求已经使现有系统达到了极限。在不远的将来，将需要移动的Gb/s便携式和可穿戴的无线节点，这将需要频谱效率的显著改进。 这项工作提出了一个综合的研究概念，它汇集了创新的波束控制天线阵列和干扰免疫波形和算法。迄今为止，为便携式和可穿戴无线应用开发的大多数天线和阵列都具有固定宽波束。这使得它们非常低效，因为大部分辐射的射频功率被头部或身体吸收，导致浪费电池功率。在这项工作中，由USC领导的显着更小的形状因子天线阵列将开发利用可控寄生阵列的概念。将研究阵列增益和角度覆盖对阵列参数的依赖性，以开发新的设计规则。从系统的角度来看，努力致力于最大限度地提高异构网络策略内的频谱效率。然而，传统的频谱利用策略是为同构网络开发的，正在集成到异构网络，这是异构网络的瓶颈。为了打破这一瓶颈，USF团队提出了增强部分重叠域的概念。对于第一次，波束转向方法在移动的将结合考虑增强的部分重叠域的时间-频率利用。将开发一个系统级测试平台，以评估所提出的阵列和波形的性能。更广泛的影响这项工作的更广泛的影响包括其在波束控制天线阵列和干扰免疫波形/算法领域产生新的基础知识的潜力，为未来的高容量便携式/可穿戴无线应用。这将对商业和军事通信领域产生影响。直接的有形成果将是一个系统级的测试平台，将提供结果，成果和设计准则，以未来的设计师。这项研究还涉及到来自哥伦比亚，SC，HBCU（历史上的黑人学院和大学）机构的本尼迪克特学院的一个团队。本尼迪克特团队将开展研究和教育活动，以开发示范模块，加强未来对本科生、高中生、女性和少数民族学生的宣传和招募工作。
