Transceivers for 40 Gb/s Data Transmission over 50 m of Coaxial Cable

该项目的目标是在50米的电视电缆上以40 Gb/s的速度传输数据，相当于25个未压缩的高清数字电视并行通道。这大约比目前最先进的技术高出一个数量级，接近电缆容量的理论极限。我们将研究两种潜在的系统架构。第一种方法需要一个高功率的发射器来克服电缆的损耗。第二种方法依靠复杂的信号处理来恢复噪声数据。研究人员是多伦多大学数字通信应用高频集成电路设计领域的两位世界领先者。该项目将利用多伦多大学独特的高频集成电路特性测试设施。研究生将使用世界上最先进的制造技术。在这个为期3年的项目中，将为加拿大价值1300亿美元的信息和通信技术部门培训8 - 10名高素质人员。同时，研究成果将为加拿大通信电子行业带来强大的竞争优势。该项目由安大略省伯灵顿的Gennum公司支持，该公司是视频传输和数字通信集成电路的行业领导者。

The goal of this project is to communicate data at 40 Gb/s, equivalent to 25 parallel channels of uncompressed high-definition digital television, over 50 meters of television cable.  This is roughly one order of magnitude beyond the current state-of-the-art and close to the theoretical limit of the cable's capacity.  Two potential system architectures will be pursued.  The first requires a high-power transmitter to overcome the cable's losses.  The second relies on sophisticated signal processing to recover the noisy data. The investigators are two world-leaders in the areas of high-frequency integrated circuit design for digital communication applications at the University of Toronto.  The project will leverage the University of Toronto's unique test facilities for high-frequency integrated circuit characterization.  Graduate students will make use of the world's most advanced fabrication technologies.  During the course of the 3-year project, 8 - 10 highly qualified personnel will be trained for Canada's $130-billion information and communications technologies sector.  At the same time, the research results will confer a strong competitive advantage in communications electronics to Candadian industry.  The project is supported by Gennum Corporation of Burlington, Ontario, an industry leader in video transport and digital communications integrated circuits.
