Towards the Beyond 5G ultra-high-speed wireless system, the “virtualized terminal” system is studied. By connecting a user terminal to multiple peripheral devices over terahertz radio wave (300GHz) which are utilized as virtual antennae communicating with access points using millimeter radio wave, the spatial multiplexing capability is enhanced. In this system, the waveform is required to be robust against both phase noise from a terahertz-wave oscillator and multipath fading over the millimeter-wave since the baseband waveform is common to those frequencies. This work evaluates the effect of those factors and reveals that the effect of phase noise and multipath fading is dominant for OFDM and DFT-s-OFDM, respectively.
