Embodiment Construction

[0044]The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0045] figure 1 It is a flow chart of the dynamic test algorithm for the received signal strength of the GSM-R network. As can be seen from the figure, the algorithm mainly includes four steps: envelope detection of received signal, dynamic sampling of signal strength, dynamic estimation of fading parameters, statistical interval and number of sampling points. specifically,

[0046] Step 101: The received signal envelope is detected by the GSM-R transceiver module, and the amplitude or power of the received signal is tested, wherein the amplitude or power is linearly amplified or logarithmically linearly amplified to obtain the received signal strength;

[0047] Step 102: Dynamically sample the received signal strength according t...
