讲座内容

Massive MIMO has been considered as a key technology for future 5G wireless communications, since it has been theoretically proved to achieve orders of magnitude increase in both spectral efficiency and energy efficiency. In this talk, we will first introduce the basic principle of massive MIMO and its theoretical performance limit, where the performance under practical implementation constraints will be also investigated. Then, considering the practical challenges from the transmitter to the receiver for realizing massive MIMO, we will investigate several key techniques for practical transceiver design of massive MIMO with our recent proposed solutions, including pilot decontamination, downlink channel estimation, uplink channel feedback, uplink multi-user detection, and downlink hybrid precoding. These solutions are expected to establish a basic framework to realize massive MIMO from theory to practice. Finally, we will also discuss future promising research directions for massive MIMO, such as millimeter-wave massive MIMO,beamspace massive MIMO, massive SM-MIMO, massive MIMO with low-resolution ADC, the integration of massive MIMO with other emerging technologies such as non-orthogonal multiple access (NOMA), ultra-dense network, energy harvesting, etc.
