Method for accelerating measurement of mobile terminal total isotropic sensitivity

Abstract

The invention provides a method for accelerating the measurement of mobile terminal total isotropic sensitivity, and aims to shorten the conventional long and time-consuming tests. The method provided by the invention mainly comprises two stages. In the first stage, test power is estimated by an exponential moving average method, i.e. an in nite impulse response lter, which weights sensitivities measured by other points according to the distances of test points, and estimates the initial test power of each test point transmission terminal. In the second stage, a quick search method is used to search effective isotropic sensitivity in a quick degradation manner, thereby accelerating the search of the sensitivity of the point; and the maximum degradation interval is set to prevent connection breakage so as to prevent reconnection. If the throughput capacity drops too much, backtracking correction is carried out, so that the sensitivity of the point is obtained, and thereby the mobile terminal total isotropic sensitivity is calculated. The method provided by the invention can accelerate the measurement of the mobile terminal total isotropic sensitivity.

Description

technical field [0001] The present invention relates to an accelerated method for measuring the total omnidirectional sensitivity of a mobile terminal, in particular to a search method that utilizes initial test power estimation, rapidly decreasing test power and avoiding disconnection to obtain equivalent omnidirectional sensitivity, thus speeding up the method of measuring the total omnidirectional sensitivity. Background technique [0002] Mobile terminals such as mobile phones must undergo radiation tests in an anechoic chamber during the development process or certification stage to verify whether the mobile terminals meet the requirements of relevant test specifications. Generally speaking, the test of its receiving performance is one of the very important items, which is carried out according to the standards of the Cellular Telecommunications & Internet Association (CTIA), and the related test items include the so-called 3D Stereo Total Isotropic Sensitivity (3D Tot...

Problems solved by technology

[0004] However, according to CTIA regulations, for multi-band mobile phones, all frequency bands must be tested, and at least three communication channels must be tested for each frequency band. Therefore, there are too many test points in the prior art, and the test time Too long, and the test speed is too slow and other issues

In order to speed up the measurement speed, the existing technology proposes to increase the measurement speed by reducing the accuracy, but the benefits are not very obvious

[0005] In addition, it is not a good way to improve the measurement speed by reducing the accuracy, especially in the research and development process of mobile phones, it is often necessary to pass the TIS measurement, so the current test method is relatively slow, which will make the mobile phone test an improvement. One of the great bottlenecks in the speed of mobile phone research and development
