Abstract

The invention relates to a multiple-antenna measurement system and method based on a network analyzer and an RF (radio frequency) switch. According to the invention, the RF switch in a time-domain platform and the network analyzer in a frequency-domain platform are effectively combined. On the premise of having the advantages of frequency domain measurement, the system can be used for utilizing remote control to realize unmanned measurement and avoiding man-made interference in a measurement process on one hand, and can be used for realizing automatic measurement based on a labview software platform and effectively improving the measurement efficiency on the other hand.

Description

technical field [0001] The invention relates to a multi-antenna channel measurement system and method, in particular to a multi-antenna measurement system and method based on a network analyzer and a radio frequency switch. Background technique [0002] Existing wireless communication channel measurement platforms mainly include two types: time domain measurement platform and frequency domain measurement platform. Compared with the time-domain measurement platform, the frequency-domain measurement platform has the characteristics of large measurement bandwidth, high signal-to-noise ratio, and easy to use general laboratory instruments to build. In the prior art, a frequency domain measurement platform based on a network analyzer is used for multi-antenna channel measurement, but usually the measurement uses manual switching of antennas, which results in low measurement efficiency and poor real-time performance. Contents of the invention [0003] The technical problem ...
