Daybreak of Practical Massive MIMO System in 5G
Organizer / Chair :  Akihiro Okazaki (Mitsubishi Electric Corp.)
The 5th generation mobile telecommunication system (5G), which will be in service in 2020, is attracting much attention. Research and development is being accelerated all over the world. Massive MIMO technology enables the higher frequency bands above 6GHz for 5G, which has been consider not suitable due to its short propagation range. Also massive MIMO enables spatial multiplexing to enhance spectral efficiency drastically. Meanwhile, many challenges still exist, e.g. use of channel reciprocity, beam steering, how to implement the circuits of massive MIMO antennas etc.
In this workshop, fundamentals of massive MIMO and its direction of research and development are introduced together with perspectives from operators and system integrators points of view.

The Dark Side of S-Parameter Simulation and Measurements
Organizers :   Masayuki Kimijima (Advantest Lab.)
Chair :   Kiyomichi Araki (Tokyo Institute of Technology)
S-parameters are usually referenced to a real reference resistance of 50Ω. At times, S-parameters normalized to some complex reference impedance are used out of necessary or for convenience'sake. Since there are incompatible definitions of complex-referenced S-parameters, it is important to use the right one for your purpose. This raises the following questions: How does my EM/microwave simulator define S-parameters? Which S-parameters does my vector network analyzer (VNA) measure?
It is shown, for example, that two EM simulators from a single vendor adopt incompatible S-parameter definitions, which could lead to possible mishaps unless the user is careful.
