- Abstract
This study studies the multiple-input–multiple-output (MIMO) performance in a tunnel scenario for the millimetre-wave (mm-wave) band. We simulated and measured channel impulse response at 28 GHz for grids of transmitters and receivers to study the feasibility of mm-wave MIMO system for metro communication in tunnel environment. The ray-tracing method was utilised to obtain the MIMO channel matrices. The performance of the channel is studied in terms of 2 × 2 and 4 × 4 MIMO, and the influences of antenna spacing on the channel capacity are investigated. The results provide a reference for the fifth-generation wireless network in the future communication-based train control system applications.
