Recently, advanced driver assistance systems (ADAS) with the keyword of “safety” have attracted attention in the world. Many mega-suppliers (Tier 1) and the others have been carrying out development for safe systems using cameras, lasers, and millimeter-wave radar to realize a self-driving system in the near future. Fujitsu Laboratories has been developing millimeter-wave monolithic microwave i...

Key fe...

Millimeter-wave mesh networks have the potential to provide cost-effective highbandwidth solutions to many current bandwidth-constrained networks including cellular backhaul. However, the availability of such networks is severely limited due to their susceptibility to weather, such as precipitation and humidity. In this paper, we present a rigorous approach to survivable millimeter-wave mesh ne...

Abstract Decoupling transmission line (TL) is a low characteristic impedance TL that is used for isolating DC and RF signals in millimeter-wave CMOS circuits. Low characteristic impedance makes the direct measurements difficult for characterization. A shunt characterization method is presented for the characterization. In this method, the S-parameters are calculated directly. Nevertheless, the ...

In this paper, we introduce developed technologies for millimeter-wave inter-vehicle communication (IVC) system in intelligent transport systems (ITS), especially propagation characteristics of 60 GHz band for the system design of IVC. First we introduce the outline of an IVC system using millimeter wave and its research subjects. Next we show experimental results of propagation characteristics...

Three dimensional (3D) terahertz (THz) imaging or THz tomography has recently proven to be useful for non-destructive testing of industrial materials and structures. In place of previous imaging techniques such as THz pulse or continuous wave (CW) radar, we propose a THz optical coherence tomography (OCT) using frequency-swept THz sources, and demonstrate 3D imaging. In addition, we further app...

This invited paper details some of the hardware modelling and impairment analysis carried out in the EU mmMAGIC project. The modelling work includes handset and Access Point antenna arrays, where specific millimeter-wave challenges are addressed. In power amplifier related analysis, statistical and behavioural modelling approaches are discussed. Phase Noise, regarded as a main impairment in mil...
