This Small Business Innovation Research (SBIR) Phase I project targets significantly increased throughputs and distances for broadband access over landline infrastructure in both urban and suburban/rural environments. For many underserved areas, it will offer the only low-cost broadband access alternative to costly, inefficient satellite coverage. In the physical-layer communication system being developed, conventional Fourier Transform (FT) based Discrete-Multi-Tone (DMT) techniques are replaced with the more spectrally efficient Wavelet-based Adaptive Filter Bank Modulation (AFBM) patented technology. A key aspect of this innovation is in the adaptive nature of its modulation method, optimizing use of available channel capacity. The project will comprise both in-depth theoretical analysis, at the algorithmic level, as well as implementation challenges, where innovation at the architectural level is expected to minimize system cost and power consumption. The theoretical research will target spectrum utilization maximization in the constrained copper-wire channels, which is enabled by the adaptive features of the technology combined with a novel approach to the wavelet-basis selection and its use in the modulation. Based on preliminary analysis and experimentation, it is anticipated that this project will result in the doubling of areal coverage, or doubling of throughput at fixed distances, compared to competing copper-wire solutions. The broader impact/commercial potential of this project will be to enable broadband service to the approximately 20 million households in the US, primarily rural, which cannot receive broadband service over existing infrastructure, other than expensive, inefficient satellite service. With this system solution, a large majority of those households could be provided with AFBM-enabled broadband access. Furthermore, AFBM will enable telco providers to better compete in areas where cable exists. Deployment will be via a business model that is to be a fabless semiconductor supplier to multiple telco equipment manufacturers, who have conveyed their pressing need for the throughput and range performance enhancements offered by this technology. Service providers indicate strong demand for high-data-rate "triple-play" service as an improvement over VDSL2, and also for T1 replacement in the cellular backhaul infrastructure, in addition to the need for rural long-reach solutions. Societal benefits include providing broadband service to previously-unreachable homes. In addition, AFBM, protected by several patents, can serve as a platform technology in wireless, coax, and power-line applications. Collaborative research with local universities will serve to steer academic research in this field towards the actual needs and interests expressed by service providers, thus advancing the related fields in communication theory.

这项小型企业创新研究（SBIR）I期项目的目标大大增加了城市和郊区/郊区环境中座机基础设施宽带访问的吞吐量和距离。 对于许多服务不足的地区，它将提供唯一的低成本宽带访问替代方案，可替代昂贵，效率低下的卫星覆盖范围。 在开发的物理层通信系统中，基于常规的傅立叶变换（FT）的离散 - 元音（DMT）技术被基于频谱高效的自适应滤波器库调制（AFBM）的技术取代。这项创新的一个关键方面是其调制方法的自适应性质，优化了可用的通道容量的使用。该项目将在算法层面以及实施挑战上构成深入的理论分析，在这些挑战中，在建筑层面上的创新有望最大程度地减少系统成本和功耗。理论研究将在受约束的铜线通道中靶向最大化频谱利用率，这是通过该技术的自适应特征与新型小波 - 基础选择及其在调制中的使用相结合的。 根据初步分析和实验，与竞争性的铜线解决方案相比，该项目将导致面积覆盖率增加一倍，或在固定距离上增加一倍。 该项目的更广泛的影响/商业潜力将是为美国大约2000万户家庭提供宽带服务，主要是农村，这些家庭无法获得现有基础设施的宽带服务，而不是昂贵，效率低下的卫星服务。借助此系统解决方案，大多数家庭都可以提供支持AFBM的宽带访问。此外，AFBM将使电信提供商能够更好地在存在电缆的区域竞争。部署将是通过商业模式，该模型将成为多个电信设备制造商的平淡无奇的半导体供应商，他们已经传达了对该技术提供的吞吐量和范围性能增强功能的迫切需求。服务提供商表明，除了需要农村长期范围的解决方案之外，服务提供者对VDSL2的高度“三重播放”服务的需求强劲，并且对蜂窝回程基础设施中的T1替换也有很高的需求。社会福利包括为以前不可用的房屋提供宽带服务。此外，受多项专利保护的AFBM可以用作无线，同轴电缆和电力线应用程序的平台技术。 与当地大学的合作研究将有助于将学术研究引导到服务提供商所表达的实际需求和利益，从而促进交流理论中的相关领域。
