PERFORMANCE INDICATOR DETERMINATION METHOD AND APPARATUS, AND DEVICE AND COMPUTER STORAGE MEDIUM

Disclosed in the present application are a performance indicator determination method and apparatus, and an electronic device and a computer storage medium. The performance indicator determination method comprises: in a first test environment and a second test environment, testing preset indicators of a relay-open communication system, so as to obtain a first test result and a second test result (100), wherein the preset indicators comprise a Q value and a linear signal-to-noise ratio (SNR); determining an external SNR value of the system on the basis of the first test result and the second test result (101); and determining an inherent SNR value of the system on the basis of the external SNR value, and a linear SNR, a nonlinear SNR and a guided acousto-optic wave Brillouin scattering (GAWBS) SNR, which are acquired (102). La présente invention concerne un procédé et un appareil de détermination d'indicateur de performance, ainsi qu'un dispositif électronique et un support d'enregistrement informatique. Le pr
