This Small Business Innovation Research Phase 2 project targets the realization of a cost-effective solution for achieving increased data throughputs in the crosstalk-constrained copper-medium-based cellular and access backhaul networks, to address the growing demand for capacity experienced in them. Existing equipment, confined to the use of twisted-pairs due to the unavailability of fiber in most locations, often avoids the use of spectrally efficient VDSL, whose high-capacity comes at a cost of vulnerability to interference. The technology developed in Phase 1 of this project, and its implementation in hardware and software as part of the Phase 2 project, will effectively address this vulnerability of VDSL and recover most of its potential capacity through crosstalk cancellation. The company?s key innovation is in non-iterative, low-latency, reduced-complexity, dynamic interference cancellation algorithms, which greatly enhance performance while requiring less than 10% of silicon-area increase in existing VDSL2 multi-channel solutions. The project will involve both research and development aspects, as well as system implementation challenges associated with the minimization of complexity and power consumption. Based on the Phase 1 project?s successful validation of the technology?s critically needed throughput enhancements and its commercial potential, it is anticipated that this technology will be widely incorporated in copper-based equipment. The broader impact/commercial potential of this project is in extending the useful life of the existing in-ground copper infrastructure, thus allowing equipment providers to continue to focus their resources on delivering ever-increasing bandwidths, while also offsetting the high expense of new fiber deployment. Benefits are also realized through the company?s partnerships with universities, where the company works closely with key faculty and with students, provides seminars, and has an ongoing internship program that results in the full-time hiring of graduates. According to publicly available reports, mobile data traffic in North America is expected to increase by a factor of over 20 by the year 2015. This massive increase in data consumption, brought on primarily by the rapid adoption of smart-phones and bandwidth-intensive applications, is already placing an enormous burden on the backhaul infrastructure, which carries telecommunications for cellular, internet and landline voice traffic. Resolution of the bandwidth congestion requires significant improvement in telecom infrastructure including backhaul and access, both of which are largely copper-based in North America. The company?s interference-mitigation technology will address this problem in a cost-effective manner by allowing the growing demand for bandwidth to be satisfied with the existing infrastructure.

这个小企业创新研究第二阶段项目的目标是实现一种经济有效的解决方案，以在串扰受限的基于铜介质的蜂窝和接入回程网络中实现更高的数据吞吐量，以满足日益增长的容量需求。由于大多数地方没有光纤，现有设备只能使用双绞线，通常避免使用频谱效率高的VDSL，其高容量是以易受干扰为代价的。本项目第一阶段开发的技术，以及作为第二阶段项目一部分的硬件和软件实现，将有效解决VDSL的这一漏洞，并通过串扰消除恢复其大部分潜在容量。公司吗?其关键创新在于非迭代、低延迟、降低复杂性、动态干扰消除算法，该算法大大提高了性能，同时只需要比现有VDSL2多通道解决方案增加不到10%的硅面积。该项目将涉及研究和开发方面，以及与最小化复杂性和功耗相关的系统实现挑战。基于第一期项目？该技术是否成功验证？由于其迫切需要的吞吐量增强及其商业潜力，预计该技术将广泛应用于铜基设备。该项目的更广泛影响/商业潜力在于延长现有地下铜缆基础设施的使用寿命，从而使设备供应商能够继续将资源集中在提供不断增加的带宽上，同时也抵消了新光纤部署的高昂费用。福利也是通过公司实现的吗？在与大学的合作中，公司与主要教师和学生密切合作，提供研讨会，并有一个正在进行的实习计划，结果是全职雇用毕业生。根据公开的报告，到2015年，北美的移动数据流量预计将增长20倍以上。由于智能手机和带宽密集型应用的迅速普及，数据消费的巨大增长已经给承载蜂窝、互联网和固定电话语音通信的回程基础设施带来了巨大的负担。带宽拥塞的解决需要电信基础设施的重大改进，包括回程和接入，这两者在北美主要是基于铜的。公司吗?S干扰缓解技术将以经济有效的方式解决这一问题，允许现有基础设施满足对带宽日益增长的需求。
