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.

拉瓦尔大学的一个研究小组将与工业合作伙伴和赞助商InterDigital Canada Inc.密切合作，一项研究计划，旨在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，其复杂性降低，并且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的吞吐量和性能是用单个天线实现的，从而显著降低制造成本、功耗和物理设备尺寸。先进的LDPC编解码器的设计，在拉瓦尔最近的研究成果的基础上，也计划。InterDigital是先进通信算法和技术的世界领导者，拥有令人印象深刻的专利组合，基本上许可给所有主要电信运营商。InterDigital Canada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多名专职研究人员，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，并能够将这些项目转化为商业成功。拟议的研究计划将在802.11n和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，开发的技术可能会影响即将出台的标准。
