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.]

ECS-0636512D。新墨西哥州州立大学博拉分校由高带宽自由空间光链路和较低速率RF链路组成的混合链路可以提供高速但鲁棒的连接。 在过去，构成链路已经相对于调制和编码被分开考虑。 在本研究计划的预算下，我们提出以下研究：1）研究混合链路的联合编码与调制技术，包括Turbo码、LPDC码和格形码的联合解调与译码。 这些技术的重要设计方面将被考虑。 将研究最佳检测/解码技术。 将研究光链路和射频链路之间的有效数据共享。 [高级人员支助的减少导致对代码的某些设计方面的关注减少，并减少了次优但低复杂性技术的开发。2)开发一个实验测试平台，用于研究混合链路和验证新的数据传输结果。 [原提案不变。]智力成果：将提出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。 重要的新思想和新技术将被开发和出版。[原提案不变。]更广泛的影响：成果将适用于其他类型的混合链路，并将导致性能的改善。 该研究将加强NMSU的教师合作，并在光学，通信和RF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，研究生将接受通信相关领域的培训。【本科生培养被取消。】
