Advanced algorithms and implementations for broadband wireless transceivers

L的拉瓦尔大学的一个研究团队将与行业合作伙伴和赞助商InterDigital Canada Inc.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高效的硬件实现，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)系统中分离多个输入数据流的技术，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，因此显著降低了制造成本、功耗和物理设备尺寸。基于Laval最近的研究成果，高级LDPC编解码器的设计也在计划中。InterDigital是先进通信算法和技术的世界领先者，拥有令人印象深刻的专利组合，几乎授权给所有主要的电信公司。InterDigital Canada计划明年在加拿大的研发支出超过700万美元。InterDigital在蒙特利尔拥有40多名敬业的研究人员，是一家具有前瞻性的公司，愿意投资于具有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。拟议的研究计划将部署在802.11n和正在制定的3G LTE标准的背景下，与InterDigital的路线图理想地保持一致。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对即将到来的标准产生影响。

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.
