The millimeter wave (mmWave) communications and massive multiple-input multiple-output (MIMO) are both widely considered to be the candidate technologies for the fifth generation mobile communication system. It is thus a good idea to combine these two technologies to achieve a better performance for large capacity and high data-rate transmission. However, one of the fundamental challenges is the characterization...
Achieving a high data rate is one of the key challenges for the next-generation wireless communication systems. This goal requires large bandwidth which is only available at high frequency band. For any wireless system, the ultimate performance limit is determined by the propagation channel. In this paper, measurement-based characterization for corridor channel at 15 GHz with 1 GHz bandwidth is presented...
Measurement uncertainty provides a quantitative reference to choose appropriate instruments and measurement methods. This paper focuses on the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. For frequency domain channel measurement, the measurement instrument, Vector Network Analyzer, need to be calibrated before measurement. The uncertainty...
As an important candidate technologies of 5th generation mobile communication system (5G), massive MIMO is able to make full use of space resources, and effectively improves the spectrum efficiency, thus helps to solve the current condition of the shortage of spectrum resources. In order to study the massive MIMO technology, the radio channel characteristics, which is different to the conventional...
This paper investigates the measurement uncertainty introduced by measurement instruments in frequency domain channel measurement systems. The uncertainty is a quantitative indication of the quality of the measurement results, so it provides a quantitative reference to chose appropriate instruments and measurement methods. The uncertainty analysis is based on Monte Carlo method. To account for the...
