Abstract
Since 5G expects using mmWave frequency band, the mmWave channel sounding system, which are used to characterise the various mmWave wireless channel models, these days, become a very hot topic for 5G. In this paper, we mainly focus on how to setup mmWave MIMO channel sounding system with commercial instruments to fulfill the 6 major technical challenges foresee in 5G as well as focusing on the main channel measurement requirements: • The use of mmWave frequency band • The use of ultra-broad bandwidth • The use of massive MIMO.
Then we provide our considerations on how to best address these technical challenges based on the last generation of mmWave/microwave instrumentation, measurement techniques and capabilities. At last, we propose a reference prototype system design for 5G mmWave MIMO channel sounding system, the functionalities and where performance of the prototype system are discussed.
