Increasing demand for wireless communication has made spectrum a scarce commodity. Mobile data traffic in Canada is slated to increase 7-fold over 2014 levels by 2019. In response, Industry Canada is trying to make new spectrum available around 600MHz and 3500MHz for commercial providers, but this will require commissioning and deploying new equipment at great expense. At the same time, our use of unlicensed spectrum (around the 2.4 GHz and 5 – 6 GHz, for example) is growing even faster than that of the licensed spectrum, and therefore seeing tremendous congestion.******Technologies to alleviate these spectral constraints are now known to communication theorists, but they must be adapted to permit their implementation in inexpensive integrated circuits (ICs). Specifically, “Massive MIMO” is a wireless technology that relies upon hundreds or even thousands of antennas at each fixed terminal (i.e. central router or base-station). All antennas transmit and receive signals in concert to hundreds of users simultaneously using the same frequencies, thereby permitting tremendous reuse of the spectrum. Orders-of-magnitude increases in communication bandwidth are theoretically achievable without increasing spectrum or radiated-power limits. ******The tremendous potential of Massive MIMO has made it a key part of wireless technology roadmaps worldwide, but innovation on mixed analog-digital integrated circuit design is needed to make it practical. Massive MIMO is seen as a necessary tool for meeting wireless bandwidth demands in the coming decades, and is implicit in Canada's wireless regulatory policies. However, these roadmaps and assumptions are already being questioned because the analog/mixed-signal IC signal processing required for a straightforward implementation of Massive MIMO is impractical. This proposal seeks analog integrated signal processing technologies to complement existing communication technologies and enable practical and inexpensive Massive MIMO communication.******Graduate students engaged in the program will undertake system-level modeling and simulation of communication links, as well as integrated circuit design and characterization in UofT labs. Their experience and training is in high demand from Canadian companies working to establish or maintain their foothold in these markets. Hence, the proposed research program will benefit Canada via the technological leadership of its HQP, and by accelerating the wide availability of next-generation inexpensive wireless broadband.

对无线通信的需求不断增长，使频谱变得稀缺。到2019年，加拿大的移动数据流量已增加了2014年的7倍。为了响应，加拿大工业公司正试图为商业提供商提供新的频谱，而新频谱可用于600MHz和3500MHz，但这将需要以巨大的费用进行调试和部署新设备。 At the same time, our use of unlicensed spectrum (around the 2.4 GHz and 5 – 6 GHz, for example) is growing even faster than that of the licensed spectrum, and therefore seeing tremendous congestion.****Technologies to alleviate these spectral constraints are now known to communication theorists, but they must be adapted to permit their implementation in inexpensive integrated circuits (ICs).具体而言，“大型MIMO”是一种无线技术，它依赖于每个固定端子（即中央路由器或基站）的数百甚至数千个天线。所有天线都会在一致之间传输并接收信号向数百名使用相同频率的用户传输，从而允许频谱的大量重复使用。通信带宽的稳定性在理论上是成功的，而无需增加频谱或辐射功率限制。 *****巨大的MIMO的巨大潜力使其成为全球无线技术路线图的关键部分，但是需要对混合模拟数字综合电路设计进行创新才能使其实用。在未来几十年中，大量的MIMO被视为满足无线带宽需求的必要工具，并且隐含在加拿大的无线监管政策中。但是，这些路线图和假设已经受到质疑，因为直接实施大规模MIMO所需的模拟/混合信号信号处理是不切实际的。补充现有通信技术并实现实用且廉价的大规模MIMO通信的技术。他们的经验和培训是加拿大公司的高需求，他们在这些市场中建立或保持其立足点。因此，拟议的研究计划将通过其HQP的技术领导，并通过加速下一代廉价无线宽带的广泛供应来使加拿大受益。
