Embodiment Construction

[0024] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] The invention relates to a WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) mobile communication system, especially a WCDMA / HSDPA / HSUPA terminal maximum output power consistency test method and device.

[0026] The invention solves the dilemma in the prior art that when the HSDPA and HSUPA technologies are introduced into the WCDMA mobile terminal, the channel configuration increases, and the maximum output power test time and test accuracy of the mobile terminal need to be improved urgently.

[0027] Figure 1A It is a block diagram of a maximum transmission power testing device for a mobile terminal according to the present invention. Such as Figure 1A As shown, the maximum transmission power test device of the present invention includes: a parameter setting module 102, which is us...

Abstract

A test device of maximum emission power consists of parameter setting module for setting up radio frequency parameter and for configuring composite channel as well as for setting mobile terminal to be entered into loop test, power gain regulation module for estimating signal to jamming ratio of channel and for regulating power gain according to estimation value and D-value of signal to jamming ratio, maximum emission power confirming module for emitting signal and calculating maximum emission power of signal under condition that power gain is remained unchanged.

Description

technical field [0001] The present invention relates to the communication field, in particular to a maximum transmission power testing device and method for a mobile terminal. Background technique [0002] The maximum transmit power of a mobile terminal is an index used to measure its maximum transmit capability, and the compressed power point is the capability of its transmit power to increase with input power. Generally speaking, the power amplifier in a mobile terminal will increase linearly as the input signal power of the terminal increases, but when the output power exceeds the compression point and approaches the maximum transmit power, the amplifier gradually exhibits nonlinear characteristics. The nonlinear distortion of the power amplifier will cause it to generate new frequency components, such as the second harmonic and two-tone beat frequency for the second-order distortion, and the third harmonic and multi-tone beat frequency for the third-order distortion. If...
