TCHCS: Efficient communications through parallel RF and optical links

ECS-0636512D。由高带宽自由空间光链路和低速率射频链路组成的混合链路可以提供高速而健壮的连接。过去，关于调制和编码，构成链路被分开考虑。1)研究混合链路的联合编码和调制技术，包括Turbo码、LPDC码和网格编码的联合解调和译码。将考虑这些技术的重要设计方面。将研究最佳的检测/译码技术。将研究光链路和射频链路之间的有效数据共享。[高级人员支持的减少导致对代码的某些设计方面的关注较少，以及次优但低复杂性技术的开发较少。]2)开发用于研究混合链路和验证新的数据传输结果的实验试验台。智力优势：将产生联合调制和编码的新方法。实验室工作将补充和加强理论工作。重大的新想法和新技术将被开发和出版。更广泛的影响：结果将适用于其他类型的混合链接，并将导致性能改进。这项研究将加强NMSU的教师合作，并在光学、通信和射频领域建立基础设施和专业知识。教育是该计划的一个重要方面，研究生将接受与通信相关的领域的培训。[本科生培训已被取消。]

ECS-0636512D. Borah, New Mexico State UniversityA hybrid link, consisting of a high bandwidth free space optical link and a lower rate RF link can provide high speed yet robust connectivity. In the past, the constituting links have been considered separately with respect to modulation and coding. We propose the following research under the revised budget for this project:1) Investigate joint coding and modulation techniques for the hybrid link including joint demodulation and decoding with turbo codes, LPDC codes, and trellis codes. Important design aspects of these techniques will be considered. Optimal detection/decoding techniques will be studied. Efficient data sharing between the optical and RF links will be investigated. [Reduction in senior personnel support results in less attention to certain design aspects of the codes and less development of suboptimal but low complexity techniques.]2) Develop an experimental testbed for studying the hybrid link and for validating the novel data transmission results. [Unchanged from original proposal.]Intellectual merit: Novel approaches to joint modulation and coding will be produced. Laboratory work will complement and strengthen theoretical work. Significant new ideas and techniques will be developed and published. [Unchanged from original proposal.]Broader impacts: Outcomes will be applicable to other types of hybrid links and will lead to performance improvements. The research will strengthen faculty collaboration at NMSU and build infrastructure and expertise in optics, communications and RF areas. Education is an important aspect of the program and graduate students will be trained in communications related fields. [Undergraduate student training has been removed.]
