BRIGE: Implementation of a Multi-Signal Real-Time Digital Receiver with High Resolution Spectral Estimation Capability on a Hybrid High Performance Computing Platform

智力优势：该bridge项目的目标是建立创新研究，将实现能够在混合高性能计算平台上进行高分辨率频谱估计的多信号实时数字接收机。主要的工作将集中在有效地实现硬件，以提高数字接收机的性能比其前身。技术包括信号处理任务的智能划分，将利用现成的图形处理单元（GPU）和现场可编程门阵列的最佳特性来增加接收器的并行处理能力，将被彻底研究。所提出的接收机设计能够提供高分辨率频谱估计，其性能将比其前身有显着改善，并且可以同时检测多达5个信号，具有高瞬时动态范围和频率分辨率。这种性能增强可归因于以下因素：1)使用具有更高采样率和精度的模数转换器，2)使用4096点快速傅立叶变换来执行高分辨率光谱分析，以及3)使用可以提供性能加速的GPU。更广泛的影响：拟议的研究通过将一些有意义的教育和推广活动与拟议的研究相结合，创造了使科学和工程对代表性不足的群体更具包容性的方法。从教育的角度来看，拟议的工作将为加州州立大学富勒顿分校的本科生提供高性能计算（HPC）和数字接收机技术领域的研究经验。其他计划的教育活动是将研究成果整合到核心计算机工程课程中，并为计算机工程本科生引入高性能计算的新专业课程。推广工作还将使当地高中和社区大学中代表性不足的少数族裔学生接触到高性能计算。

Intellectual Merit: The objective of this BRIGE project is to establish innovative research that will implement a multi-signal real-time digital receiver capable of high-resolution spectral estimation on a hybrid high-performance computing platform. The main effort will center on efficiently implementing the hardware to enhance the performance of the digital receiver over its predecessor. Techniques including intelligent partitioning of the signal processing tasks that will utilize the best features of both off-the-shelf graphics processing unit (GPU) and field-programmable gate array to increase the parallel processing capability of the receiver will be thoroughly investigated. The proposed receiver design capable of high-resolution spectrum estimation will provide remarkable improvement in performance over its predecessor and can detect up to 5 signals simultaneously with high instantaneous dynamic range and frequency resolution. This performance enhancement can be attributed to factors such as: 1) use of an analog-to-digital converter with a higher sampling rate and precision, 2) use of 4096-point fast Fourier transform to perform high-resolution spectral analysis, and 3) use of a GPU that can provide performance acceleration. Broader Implications: The proposed research creates ways to make science and engineering more inclusive to underrepresented groups by integrating a number of meaningful education and outreach activities with the proposed research. From an educational perspective, the proposed work will provide research experience to undergraduate students, at the California State University, Fullerton in the area of High Performance Computing (HPC) and digital receiver technology. The other educational activities planned are integration of research findings into core computer engineering courses and introduction of a new specialty track in High Performance Computing for Computer Engineering undergraduates. The outreach efforts will also be made to expose underrepresented minority students at local high schools and community colleges to high performance computing.
