Advanced algorithms and implementations for broadband wireless transceivers

拉瓦尔大学的一个研究小组将与工业伙伴和赞助商加拿大InterDigital公司密切合作，开展一项研究计划，以创建创新和高性能的信号处理算法及其有效的硬件实现，以支持先进的宽带无线收发器。这些算法包括在MIMO（多输入，多输出）系统中分离多个传入数据流的技术，降低了复杂性，并具有最大程度的灵活性，以适应不断变化的信道和干扰条件。一个计划的途径是研究虚拟MIMO接收，其中MIMO的吞吐量和性能是通过单个天线实现的，从而显着降低制造成本，功耗和物理设备尺寸。还计划在Laval最近的研究成果基础上设计先进的LDPC编解码器。InterDigital是先进通信算法和技术的全球领导者，拥有令人印象深刻的专利组合，它基本上授权给所有主要电信公司。InterDigital加拿大公司计划明年在加拿大投入超过700万美元用于研发。InterDigital在蒙特利尔拥有40多名专门的研究人员，是一家具有前瞻性的公司，愿意投资于基础性的长期研究项目，并有能力将这些项目转化为商业成功。拟议的研究计划将在802.11n和正在开发的3G LTE标准的背景下进行部署，与InterDigital的路线图非常一致。预计，通过InterDigital积极参与各种标准机构和工作组，所开发的技术可能会影响即将出台的标准。

A research team at l'Université Laval will undertake, in close collaboration with industrial partner and sponsor InterDigital Canada Inc., a research program to create innovative and high performance signal processing algorithms and their efficient hardware implementations to support advanced, broadband wireless transceivers. These algorithms include techniques to separate multiple incoming data streams in MIMO (multiple input, multiple output) systems with reduced complexity, and with a maximum degree of flexibility to adapt to changing channel and interference conditions. One planned avenue is the investigation of virtual MIMO reception, where the throughput and performance of MIMO is achieved with a single antenna, thus reducing significantly fabrication cost, power consumption and physical device size. The design of advanced LDPC codecs, building upon recent research results at Laval, is also planned. InterDigital is a world leader in advanced communications algorithms and techniques with an impressive patent portfolio which it licenses to essentially all major telecom players. InterDigital Canada plans to spend more than 7M$ in Canada in R&D next year. Having a dedicated research staff of more than 40 people at its Montreal location, InterDigital is a forward-looking corporation, willing to invest in long-term research projects which are fundamental in nature, and capable of turning these into commercial successes. The proposed research program, which will be deployed within the contexts of the 802.11n and 3G LTE standards-in-progress, is ideally aligned with InterDigital's roadmap. It is expected that the technologies developed could influence upcoming standards, through InterDigital's active involvement in various standards bodies and workgroups.
