Title: The Deep Learning in Physical Layer Communications

It has been demonstrated recently that deep learning (DL) has great potentials to break the bottleneck of communication systems. In this talk, we introduce our recent work in DL in physical layer communications. DL can improve the performance of each individual (traditional) block in communication systems or jointly optimize the whole transmitter or receiver. Therefore, we can categorize the applications of DL in physical layer communications into with and without block processing structures.

For DL based communication systems with block structures, we present joint channel estimation and signal detection based on a fully connected deep neural network, model-drive DL for signal detection, and some experimental results. For those without block structures, we provide our recent endeavors in developing end-to-end learning communication systems. At the end of the talk, we provide some potential research topics in the area.

For any further questions, please go to the local host site to find contact information.

Dr. Geoffrey Li is a Professor with the School of Electrical and Computer Engineering at Georgia Institute of Technology. He was with AT&T Labs – Research for five years before joining Georgia Tech in 2000. His general research interests include statistical signal processing and machine learning for wireless communications.
In these areas, he has published around 500 referred journal and conference papers in addition to over 40 granted patents. His publications have cited by 35,000 times and Thomson Reuters almost every year since 2001 have listed him as the World’s Most Influential Scientific Mind, also known as a Highly-Cited Researcher. He has been an IEEE Fellow since 2006.

Title: Massive MIMO: History, Evolution and Future

In 2011 researchers at Huawei Technologies Sweden AB proposed a new type of base station architecture with the aim to increase capacity by about 1000 % compared to the state-of-the art 2T2R base station used by most operators at this time. At first the possibility of such an increase of capacity was met with skepticism. Not so strange considering that most development projects at this time focused on increasing efficiency of base station power amplifiers, algorithms, or antenna sector coverage by single percentage figures. However, in 2013 the Swedish team had through hard work and many innovative ideas convincingly shown the feasibility of the solution, which by this time was known under the name Massive MIMO. In 2014 Huawei built its first large scale lab prototype in Shanghai and performed tests with China Mobile. In 2015 the first commercial Massive MIMO base station was deployed by China Mobile. In 2018 Huawei’s Massive MIMO products have seen large-scale deployment in over 40 countries, such as Japan, China, Spain, UK, and Saudi Arabia.
This talk will give an overview of the benefits of Massive MIMO, the history of Massive MIMO at Huawei, some recent performance figures and discuss possible future developments of Massive MIMO.

Mats Andersson has three university degrees (Lic. Eng., M. Sc. and B.A.) and more than 30 years international wireless and telecom experience working at various engineering and management positions at Ericsson (in Canada, England and Sweden) He left Ericsson 2006 to become CEO of the start-up company Bluetest AB. During his 5 years as CEO Bluetest grew rapidly to become the world leading MIMO Over-The-Air (OTA) test company. In 2011 Mats joined Huawei Technologies Sweden AB as Site and System Manager Radio Base Systems in Gothenburg. During his time at Huawei the Gothenburg office became a world leading competence center for Higher Order MIMO and Massive MIMO base stations. In 2014 Mats started the company MUMIMO AB to focus on innovation and business development for small and large wireless companies. Since September 2018 Mats is back at Huawei Technologies Sweden AB as CTO, Wireless R&D, Stockholm R&D Center, Sweden. He also holds roles as Chairman of the Board of Forsway Scandinavia AB, SweGaN AB, Satcube AB and MUMIMO AB and is a Board member of Bluetest AB and Gefle Testteknik AB.
