This paper describes the implementation of a Doppler spectrum measurement platform for narrowband frequency-dispersive vehicle-to-vehicle (V2V) channels. The is based on continuous-wave (CW) channel sounding approach widely used path-loss and large-scale fading measurements, but whose effectiveness to measure V2V channels not equally known. method implemented using general-purpose hardware in c...

Abstract Photoacoustic Doppler flow measurement based on continuous wave laser excitation owns the merit of clearly presenting power spectra. Extending this technique to dual wavelengths can gain spectral information sample extra speed information. An experimental system with two diodes respectively operated at 405 nm and 660 is built black red dyed polystyrene beads performed. The measured spe...
