讲座名称：Recent Advances in Wireless Technology Towards B5G/6G 讲座人：Fumiyuki Adachi 教授 讲座时间：3月21日 16:00—17：00 地点：腾讯会议： 194-765-770 讲座人介绍： Fumiyuki Adachi (IEEE终身研究员)获理学士学位。分别于1973年和1984年在日本仙台东北大学获得电气工程学位。1973年4月，他加入NTT电气通信实验室，开始从事移动通信研究。1992年7月至1999年12月，他在NTT DOCOMO工作，领导一个3G及以上宽带/宽带无线接入的研究小组。他为开发3G空中接口标准，即W-CDMA做出了贡献。自2000年1月起，他一直在日本仙台东北大学工作。目前，他在东北大学国际灾害科学研究所(IRIDeS)领导一个弹性无线通信研究小组，目标是实现超越5G/6G系统。主要研究方向为无线信号处理与网络，包括多址接入、均衡、天线分集、协同传输、信道编码、无线电资源管理等。 讲座内容： Over the past 40 years, mobile communication systems have evolved from 1G to 5G. Advances in wireless technology have greately contributed to this evolution. The first lecture concerns recent advances in wireless technology towards Beyond 5G (B5G)/6G. Due to the rapid growth of broadband data services, mmWave band is utilized for 5G systems. Unfortunately, however, its deployment is rather slow. Considering that the mmWave band is indispensable for radio access in B5G/6G, it is necessary to find a way to accelerate its utilization by changing the disadvantage of the mmWave short distance communication into an advantage. Ultra-densification of radio access not only greatly improves spectral efficiency, but also makes it possible to utilize the mmWave band. This lecture will introduce the concept of scalable and flexible cell-free/distributed multi-user MIMO. 主办单位：资源保障部
