Embodiment Construction

[0038] The present invention proposes a method for processing the data obtained by the CW test. By performing distance judgment on each sampling point, redundant sampling points that do not meet the correlation requirements and sampling points that do not meet the number of Lee's theorem are deleted to ensure the accuracy of the CW test. The accuracy of the locally averaged results at the sampling point. The specific implementation manner of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] As shown in FIG. 1, FIG. 1 is a flowchart of the present invention. Steps included in Figure 1:

[0040] Step 1, calculating the distance between adjacent sampling points in the original sampling point set;

[0041] As shown in Figure 2, Figure 2 is a flowchart of step one of the present invention, and in Figure 1, this step specifically includes the following steps:

[0042] Step 101, calculating the geographical coor...

Abstract

The invention provides a data processing method of continuous wave test for propagation model tuning, which comprises: step 1, calculating the distance between adjacent sampling sites in an original sampling site aggregate; step 2, deleting a part of the sampling sites according to the distance between the adjacent sampling sites in the original sampling site aggregate, to obtain a first sampling site aggregate, the distance between the adjacent sampling sites in the first sampling site aggregate being larger than or equal to the preset threshold; step 3, deleting a part of the sampling sites from the first sampling site aggregate to obtain a second sampling site aggregate, in the second sampling site aggregate, the number of actual sampling sites within the intrinsic length being larger than the preset threshold. The invention provides also a data processing device of continuous wave test for propagation model tuning, which comprises: a computation module, a first data processing module, a second data processing module and an output module. The invention can realize the judgment of sampling site number within the intrinsic length, which complies with the Lee's criterion, in the test with failure to correctly control the motion speed of the test terminal, and ensure the accuracy of the sampling sites.

Description

technical field [0001] The invention relates to the field of wireless communication networks, in particular to a method and device for processing data obtained from a continuous wave (Contious Wave, CW) test for propagation model correction in network construction. Background technique [0002] CW testing is currently the most commonly used method for propagation model correction. The propagation model is used to predict the influence of terrain, obstacles and man-made environment on path loss in radio wave propagation. The work of propagation model calibration is to find a propagation model and the parameters in the model that are more suitable for the local scene. [0003] The principle of propagation model correction for continuous wave testing is: the transmitter remains in a constant state, the receiver moves within the signal coverage of the transmitter, and the received signal strength changes with the position of the receiver, then the path loss in the propagation p...
