講學(xué)題目1: Huffman Coded Modulation for MIMO
講學(xué)時(shí)間：2019.01.12下午14:00-15:30
講學(xué)地點(diǎn)：哈工大科學(xué)園2A棟1013會(huì )議室
報告內容簡(jiǎn)介：
Massive MIMO has been considered as a promising PHY technical solution for 5G cellular networks. Antenna switch enables multiple antennas to share a common RF chain. It also offers an additional spatial dimension, i.e., antenna index, which can be utilized for data transmission via both signal space and spatial dimension. In this talk, a Huffman coding based adaptive spatial modulation will be presented that generalizes both conventional spatial modulation and transmit antenna selection. Through Huffman coding, the transmit antennas can be activated with different probabilities. Numerical results show that the proposed Huffman coded spatial modulation offers considerable performance gains over conventional spatial modulation or transmit antenna selection.
講學(xué)題目2: Millimeter Communications for UAV Systems
講學(xué)時(shí)間：2019.01.12 下午15:30-17:00
講學(xué)地點(diǎn)：哈工大科學(xué)園2A棟1013會(huì )議室
報告內容簡(jiǎn)介：
With the growing demand of real-time communications in anywhere for anyone, UAV communications has been developed, as the UAV can be simply deployed in cities, remote areas, over the seas, etc. To support the high bandwidth requests for UAV communications, millimeter wave band is considered as a promising candidate. This talk will overview some research challenges and opportunities in developing mmWave communications for UAVs, including channel modeling, beam training and tracking, dynamic routing and mmWave cellular technology.
講學(xué)題目3: Multi-panel MIMO in 5G
講學(xué)時(shí)間：2019.01.12 下午17:00-18:30
講學(xué)地點(diǎn)：哈工大科學(xué)園2A棟1013會(huì )議室
報告內容簡(jiǎn)介：
Massive MIMO is one of the key enabling technologies in 5G wireless communications. A large number of antenna elements bring extra degrees of freedom for increasing the throughput and considerable beamforming gains for improving the coverage. In practice, a large number of antenna elements can be assembled into multiple antenna panels for the purpose of cost reduction and power saving. Multi-panel MIMO is expected to become promising for millimeter-wave massive MIMO systems. This article gives an overview of multi-panel MIMO systems, including downlink, uplink, and non-coherent transmissions, and discuss research challenges and future directions of multi-panel MIMO. We also propose new multi-panel codebook design and corresponding CSI feedback design for 5G systems as well as non-coherent MIMO transmission.
