| Abstract(in English) | The sixth-generation mobile communication is being extensively studied to commercialize the services in around 2030. A frequency range of 100-300 GHz, called a sub-Terahertz band, will be used to realize very wide band transmission. In addition to the broad bandwidth, we need spatial multiplexing signal processing using a MIMO system to achieve high data-rate communication over 100 Gbps. The spectrum suffers from high attenuation in non-line-of-sight environments. Intelligent reflection surfaces (IRSs) are expected to be useful to reduce the attenuation. An IRS is composed of many reflecting elements with phase shifters, and signal processing techniques play an important role to adjust them. On the other hand, a recently presented paper reveals that the number of observed multipath components in a sub-Terahertz band is very few in indoor environments. In this talk, we address spatial-domain signal processing in the sparse sub-Terahertz band. |
