Problems solved by technology

However, from the data recorded in Table 1, it can be clearly seen that the above analysis results are not accurate, because the power of the interference signal at the first snapshot far exceeds the interference threshold, and a call drop occurs
[0008] That is to say, the existing method simply averages the interference signal power captured multiple times without considering the direction of the interference signal, so it cannot provide real and accurate grid analysis results for system simulation, making the performance of the simulation area Analysis prone to bias

Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0028] Fig. 3 is the implementation process of grid analysis in the present invention, specifically includes:

[0029] Step 301: the user distribution generation module 101 generates a user distribution for the TD-SCDMA simulation system and sends it to the simulation control platform 102, and the simulation control platform 102 triggers the static snapshot module 103 to execute once when the system with the user distribution enters a stable state Static capture.

[0030] In this step, the stable state of the TD-SCDMA simulation system is achieved by the power control performed by the simulation control platform 102. The existing Monte-Carlo simulation includes the above power control process, which will not be repeated here.

[0031] Step 302: The sta...

Abstract

The disclosed implementation method for grid analysis in TD-SCDMA comprises: generating at least one-time user distribution for the simulation system, executing static snatch when system with relative user distribution enters stable state; then recording all power message of current simulation environment, and generating real-time performance parameter for every grid in the simulation area; and calculating the average performance parameter. This invention can obtain analysis result with high reference value fit to TD-SCDMA system optimization.

Description

technical field [0001] The invention relates to TD-SCDMA network planning, in particular to a method for realizing grid analysis in a TD-SCDMA simulation system. Background technique [0002] In CDMA network planning, interference signals are usually regarded as a kind of background noise. In this way, after performing a Monte-Carlo simulation, record the power of all interference signals through static snapshots and add them directly, and then average the interference signal power obtained by multiple snapshots to obtain the background noise required for system analysis . In the above process, the interference signal is set to have no directionality, that is, the interference signal is evenly distributed. Since the general CDMA system is not sensitive to the direction of the interference signal, this method of averaging the interference signal is applicable. [0003] However, for the TD-SCDMA system, the system uses a smart antenna capable of space division filtering. Th...
