Abstract

Abstract : In this study, the authors design and implement a real‐time hardware‐in‐the‐loop (HIL) wideband high‐velocity channel emulation platform for the performance evaluation and verification of 5G mmWave systems. A novel spectral splitting & stitching method and channel partitioning algorithm are developed to synchronously combine up to eight 160 MHz sub‐channels. The HIL platform was calibrated in the time and frequency domains and then validated using back‐to‐back results from a pair of experimental 60 GHz mmWave modems. The emulated path loss was generated for an additive white Gaussian noise channel to characterise the data throughput versus signal‐to‐noise ratio for a fixed point‐to‐point deployment. The wideband emulator was then used to introduce the Doppler shifts and spreads observed in a high velocity (up to 600 km/h) mmWave channel. For a Ricean channel ( K ‐factor greater than or equal to 10 dB), negligible data throughput losses were observed for velocities up to 293.9 km/h. Using the emulator, they show that the 5G modems can achieve continuous connectivity (albeit with some throughput loss) at velocities up to 587.8 km/h. Tests were also conducted in Rayleigh channels with uniformly distributed spatial multipath. In the Rayleigh case, the maximum vehicular velocity dropped to 51.4 km/h.
