Use one-bit technique to measure the coherence in the time, frequency and space domain in a reverberation chamber

摘要

High speed data streams are everywhere in the fifth generation (5G) system measurement. To develop a high efficient and low cost 5G testbed in a reverberation chamber, the authors propose a high efficient measurement method in the time, frequency and space coherence measurement. In this study, the one-bit technique is introduced to measure the time domain, frequency domain and space domain correlations in a reverberation chamber. The coherence time, coherence bandwidth and correlated angle can all be measured using the one-bit correlation; float number calculations are simplified to logical operations which accelerate the data processing greatly. Measurements are performed to verify the results.
