| Abstract: | In order to test the diversity gain of diversity receiver,a test method based on real-time carrier-to-noise ratio measurement is proposed.By inputting two different signal-to-noise ratios and independent fading signals to the diversity receiver,the powers of the input,output signals and noise are obtained by power meter test,and the diversity gain of the diversity receiver is calculated.The application results show that the method can test the diversity gain of diversity receiver,and it is efficient and feasible. |
