研究成果

This article has provided a comprehensive investigation of recent developments and future challenges in mmWave channel sounders, measurements, and models for 5G wireless communication systems. Frequency and time domain channel sounders have been compared. Channel measurements in various indoor and outdoor scenarios for multiple mmWave bands have been investigated. Comparison of multiple mmWave bands, validation of massive MIMO properties, and measurement and modeling of human blockage effects have been shown. Different channel modeling approaches including deterministic, semi-deterministic, and stochastic modeling methods have been compared and summarized. Some future research directions have also been discussed.
