A rigorous Link Performance and measurement uncertainty assessment for MIMO OTA characterisation.
arXiv: Signal Processing, 2018Co-Authors: Min Wang, Tian-hong Loh, David Cheadle, Yongjiu Zhao, Yonggang ZhouAbstract:In this paper, a rigorous Link Performance test for MIMO OTA (multiple-input-multiple-output over-the-air) characterisation with traceable signal-to-interference-plus-noise ratio (SINR) is presented. Measurements were made with three different testbeds which represent the 4G (fourth-generation) LTE (long term evolution) SISO (single-input-single-output), 4G LTE MIMO and 5G (fifth-generation) millimetre-wave (mm-wave) MIMO communication systems, respectively, in the small antenna radiated test (SMART) screened fully anechoic chamber, screened control room and reverberation chamber at the UK National Physical Laboratory (NPL). The measurement campaign comprised of automated data acquisition of channel power, downLink (DL) & upLink (UL) error vector magnitude (EVM) and throughput. The measurement repeatability has been assessed with standard deviation plotted as error bars and the uncertainty sources in the OTA test are analysed.

A rigorous Link Performance and measurement uncertainty assessment for MIMO OTA characterisation
Loughborough Antennas & Propagation Conference 2018 (LAPC 2018), 2018Co-Authors: Min Wang, Tian-hong Loh, David Cheadle, Yongjiu Zhao, Yonggang ZhouAbstract:Spatial and polarisation diversity MIMO and massive MIMO are Key features of 5G to maximise the available throughput to a single or multiple users. As 5G develops, particularly mm-wave, over-the-air (OTA) testing will become essential because direct connection will no longer be feasible. Rigorous MIMO OTA characterisation is a serious challenge for the specification bodies and for the test-equipment manufacturers. In this paper, a rigorous Link Performance test for MIMO OTA characterisations with traceable signal-to-interference-plus-noise ratio (SINR) is presented.

Routing and Link Performance assessment of a wireless sensor network in a reverberation chamber with different absorber loading conditions
2017 XXXIInd General Assembly and Scientific Symposium of the International Union of Radio Science (URSI GASS), 2017Co-Authors: Tian-hong Loh, Ke LiuAbstract:This paper presents an assessment of data routing and Link Performance of a rhombus-shaped wireless sensor network (WSN) using four IEEE 802.15.4 compliant MICAz sensor motes in a reverberation chamber (RC) loaded with different number of absorbers at the corners. The influences of loading absorbers on the RC quality factor (Q-factor) are compared. The results show that for WSN communications without relays better Link Performance could be achieved with lower Q-factor whereas for WSN communications with relays the Link Performance degrade by the complex inter-path interferences regardless Q-factor values, which suggests future studies are necessary.
