The Third-Generation Mobile Communication Technology Propagation Model Calibration

As the third generation mobile technology development, the construction of3Gnetwork is accelerated pace. As the largest mobile operators, shaanxi mobile is3Gnetwork construction for the preparation work.Mobile communication has been developing rapidly in recent years. With theemergence of new business and new users, service carriers are paying more and moreattention to the construction of the mobile communication network. Without theaccurate radio wave propagation model, it is impossible to build a high qualitycommunication network. A relatively precise propagation model is favorable foraccurately estimating base stations’coverage range and forecasting network’s coveragecondition. In network planning, radio propagation and coverage forecasting are bothconducted on the basis of propagation models, while the classical models can notreflect the propagation characteristics of a particular environment accurately. Usingthese propagation models without calibrating may introduce serious errors into thepredicted value. Therefore, in order to obtain the propagation model reflecting the localpropagation environment with high accuracy, it requires a great deal of tests tocalibrate the radio propagation model.Signal Integrity is the natural property of the signal keeping up its originalfunctionality and being unimpaired by transmission． Being closely related to theimplementation of the3G mobile communications technologies the critical signalintegrity challenges to the system designers may be presented by physical－layercomponents during the high speed design． Combined with Chinese standard3Gmobile communications technologies signal integrity issues and the related solutionsand simulation model and software.This paper mainly analyzes the wireless transmission model of mobilecommunication system, the necessity of calibration and applied in the actual networkengineering and assessment method. CW adopted successive waves of testing methodis the third generation mobile communication of wireless communication modelcalibration, calibration model in computer software simulation through thecommunication and signal and comparison, the spread of correction model for the thirdgeneration mobile communication network planning.
