项目摘要
One key limit to spectrum utilization efficiency involves the current practice of half-duplex communication, in which a node cannot transmit and receive on the same frequency at the same time. Some recent studies have provided experimental evidence and methodologies for full-duplex communication. To date, however, all full-duplex demonstrations have been predicated on the principle that the transmitter and the receiver must generate their own radio-carrier waves independently, which in practice results in a high level of self-interference at both nodes. The objective of this CAREER project is to create reliable full-duplex wireless networks by means of reflected power.This project will pursue backscatter modulation, where electromagnetic waves are modulated and reflected by the same antenna that receives them. Within this framework, the end-user receives a signal free of self-interference. This research offers a new paradigm for two-way wireless networks: rather than avoiding self-interference as in half-duplex -- or combating self-interference as in full-duplex -- nodes will re-use the received interfering radio-carrier waves to transfer information. The results of this analysis will advance the knowledge of antenna scattering for a wide range of applications. The proposed implementation in hardware will incite an exchange between algorithm innovation and hardware implementation, pushing the limit of spectrum-efficiency communication.The principal investigator will also embed the proposed research into pedagogy by creating a center of wireless communications at Purdue University Calumet. The center will provide a range of opportunities for undergraduate and graduate students to gain direct experience in testing, evaluating, and improving backscatter modulation for full-duplex communications. Given the current pervasiveness of two-way wireless communication, the results of this research can be used to significantly increase the spectral efficiency of future wireless networks.
频谱利用效率的一个关键限制涉及半双工通信的当前实践,其中节点不能同时在相同频率上发送和接收。最近的一些研究为全双工通信提供了实验证据和方法。然而,到目前为止,所有全双工演示都是基于发射机和接收机必须独立生成自己的无线电载波的原则,这在实践中会导致两个节点的高水平自干扰。该CAREER项目的目标是通过反射功率创建可靠的全双工无线网络。该项目将采用反向散射调制,即电磁波被调制并由接收它们的同一天线反射。在此框架内,最终用户接收到无自干扰的信号。这项研究为双向无线网络提供了一个新的范例:节点将重新使用接收到的干扰无线电载波来传输信息,而不是像半双工那样避免自干扰,或者像全双工那样对抗自干扰。这种分析的结果将推进知识的天线散射的广泛的应用。在硬件上的实现将激发算法创新和硬件实现之间的交流,推动频谱效率通信的极限。首席研究员还将通过在普渡大学卡卢梅创建一个无线通信中心,将拟议的研究嵌入到教学中。该中心将为本科生和研究生提供一系列机会,以获得测试,评估和改进全双工通信后向散射调制的直接经验。鉴于目前双向无线通信的普遍性,本研究的结果可用于显着提高未来无线网络的频谱效率。
