项目摘要

Spectrum efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized. In this project, innovative spectrum efficient waveform designs are studied towards narrower mainlobe and lower sidelobe in spectrum. It has been recognized that judicious use of properly designed waveforms, coupled with advanced receiver strategies, is fundamental to fully utilizing the capacity of the electromagnetic spectrum. This project seeks innovative approaches on nested and co-prime samplers for spectrum efficiency, and subsequently applies it to wireless networks. Different waveforms designs and diversities are studied based on nested and co-prime samplers. Co-prime samplers are used for Multi-Input Multi-Output communication system. In the application to spectrum efficient wireless networks, nodes exchange information over a common wireless channel. Under different traffic scenarios and different constraints, e.g., bandwidth and signal to noise and interference ratio, the amount of data exchanged among these nodes may vary. A key question then is how the throughput capacity of wireless network improves with the new waveform design schemes and different network setup and how it grows with the number of nodes in the network. This project seeks to help reach the nation's broadband goals and the larger objective of alleviating growing pressure on limited spectrum resources. This project will attract minority and woman students to participate in the project.

频谱效率是指在特定通信系统中可以通过给定带宽传输的信息率。这是对有限频谱的有限频率的衡量标准。在这个项目中，研究了创新的频谱有效的波形设计，用于较窄的大主体行驶和频谱中的较低的侧球。人们已经认识到，正确使用正确设计的波形，再加上先进的接收器策略，这对于充分利用电磁频谱的容量至关重要。该项目寻求有关嵌套和联合选度采样器的创新方法以提高频谱效率，然后将其应用于无线网络。基于嵌套和联合选度采样器研究了不同的波形设计和多样性。联合抽样器用于多输入多输出通信系统。在频谱有效的无线网络的应用程序中，节点通过通用无线通道进行交换信息。在不同的交通情况和不同的约束下，例如带宽和信号与噪声和干扰比，这些节点之间交换的数据量可能会有所不同。然后，一个关键的问题是，无线网络的吞吐量如何通过新的波形设计方案和不同的网络设置来改善，以及它如何随着网络中的节点数量而增长。该项目旨在帮助达到国家的宽带目标，并为减轻有限频谱资源的压力增长的更大目标。该项目将吸引少数民族和女学生参加该项目。
