<p>The present invention provides a method and device for calculating the gains of multiple reception links/transmission links, and relates to the wireless communication technology field. The method includes that: one calibration signal is divided into multiple calibration signals, and each of the multiple calibration signals is respectively coupled to each reception link; the data of the frequency compensation and temperature compensation of the link to which the calibration signal before being divided into multiple signals belongs is measured; the reception link is calibrated and the correlative peak amplitude value of each reception link is obtained; a calibration link gain is obtained and each reception link gain is calculated. The device includes: a signal processing module, a splitter, and multiple directional couplers and a measurement module, wherein the signal processing module includes a signal transmission unit, a calibration unit and a calculation unit. With the invention, the workload for measuring multiple reception links gain and multiple transmission links gain in a multi-antenna system is decreased, the measurement time is saved, and the accuracy and consistency of the reception/transmission link gain are improved.</p> |
