The embodiment of the invention has at first been carried out analysis-by-synthesis to terminal in the performance of data transmission, and terminal mainly embodies aspect several by following in the performance of data transmission:
1, in the actual use of terminal, finds, because the imperfection of terminal antenna design, terminal list reveals tangible directional selectivity, all different in Data Receiving performance and data transmission performance that different angles show, therefore, the performance that can more fully investigate terminal in the Data Receiving performance and the transmission performance of a plurality of angles in conjunction with terminal.
Find in the actual use of terminal that 2, the signal to noise ratio that communication quality and terminal base band receive has bigger correlation, wherein, signal to noise ratio=available signal power/(interference power+noise power).
The high more base band that helps more of signal to noise ratio is recovered primary signal, with the transfer of data is example, the high 3dB of signal to noise ratio, data rate can improve about 10%, simultaneously, signal to noise ratio also is available signal power and the interference power that the common network of important evidence that network carries out switching judging can require this sub-district of terminal to report and adjacent sub-district.Therefore whether terminal all is very important to network and terminal accurately for the measurement of useful signal and interference.
At terminal inner, aerial high-frequency signal at first receives through antenna and the radio frequency unit processing could arrive Base Band Unit.Because the antenna and the radio frequency unit design level difference of each terminal, same signal is caused in various degree decay, cause final signal to noise ratio to have nothing in common with each other.And in use find the measurement of signal to noise ratio same closely relatedly with direction, same terminal signal to noise ratio to same signal measurement on all directions is also inequality, sometimes even differ more than the 10dB.Therefore, whether terminal can can't harm received signal and accurately measure and report, and this also is the embodiment of terminal complete machine performance.
