SBIR Phase I: 256 QAM Modem Supporting 10 Gb/s Radio

该小型企业创新研究（SBIR）第一阶段项目支持开发能够利用现有新兴毫米波（mm波）频谱的正交幅度调制（QAM）调制解调器（调制解调器）。与较低的频率分配不同，通过使用复杂的调制方案，宽的可用带宽能够支持超过1Gb/s的数据速率。尽管这样的调制解调器存在于日常使用中的大量标准产品中，但是没有一个能够被缩放以用于接近10 Gb/s的数据速率，并且毫米波信道的特性没有被容纳在它们的设计中。本项目的目标是建立这样的调制解调器的可行性和指导未来的发展，同时充分考虑到在毫米波通信链路的重要信道特性，通过彻底建模的系统在一个高层次的抽象，然后实例化的数字子系统与现有的现场可编程门阵列（FPGA）技术。这将导致一个明确的无线电发展道路，具有扩展能力。该项目的更广泛的影响/商业潜力集中在提高对毫米波频谱的理解和利用以及因此促进的技术和市场。随着对通道效应和数字信号处理算法的深入了解，用于处理它们的固件和硬件;整个毫米波范围的工作都得到了帮助。此外，毫米波产品中使用的大部分半导体技术仍处于起步阶段，因此进行的任何表征都将对指导未来的发展具有重要价值。作为一个完整的产品，使用这种先进的调制解调器的无线电将允许在世界任何地方快速，经济有效地部署运营商和企业级10 GB/s无线数据通信，并将侵入性物理中断降至最低。在目前运行有1GB/s毫米波链路的一些网络中，当现有链路已经被超额预订时，便于扩展到更大的数据速率。其他潜在的应用包括在高光谱勘测平台中使用;机载或航天器载。在任何需要极高数据速率的地方，与硬连线选项相比，这种无线电将实现快速部署和加速投资回报，并且在某些情况下将为移动的平台提供唯一的解决方案。

This Small Business Innovation Research (SBIR) Phase I project supports the development of a Quadrature Amplitude Modulation (QAM) Modulator-Demodulator (Modem) able to exploit existing emerging millimeter-Wave (mm-Wave) spectrum. Unlike lower frequency allocations, wide available bandwidths are capable of supporting data-rates in excess of 1Gb/s by using complex modulation schemes. Though such Modems exist for a multitude of standard products found in everyday use, none are capable of being scaled for use at data-rates approaching 10Gb/s and characteristics of mm-Wave channels have not been accommodated in their design. The objective of this project is to establish the feasibility and direct the future development of such a Modem while taking into full account the channel characteristics important in an mm-Wave communications link, by thoroughly modeling the system at a high level of abstraction, then instantiating the digital subsystem with existing Field Programmable Gate Array (FPGA) technology. This would result in a clear radio development path, with the ability to scale.The broader impact/commercial potential of this project center on the improved understanding and utilization of mm-Wave spectrum and the technologies and markets facilitated therefore. With an improved understanding of channel effects and the Digital Signal Processing algorithms, firmware and hardware used to deal with them; work throughout the mm-Wave range is aided. Furthermore, much of the semiconductor technology used in mm-Wave product is in its infancy, so any characterization performed would be of great value in directing future development. As a complete product, the radios using such an advanced Modem would allow fast, cost effective deployment of Carrier and Enterprise Class 10 GB/s wireless data communications anywhere in the world with a minimum of invasive physical disruption. In some networks presently running with 1 GB/s mm-Wave links, scaling to greater data-rates when the existing link has been over-subscribed is facilitated. Other potential applications include use in hyperspectral survey platforms; airborne or space borne. Anywhere extremely high data-rates are needed such radios would enable fast deployment and accelerated Return-on-Investment when compared to hardwired options, and in some cases would provide the only solution for mobile platforms.
