In the traditional GSM network planning, the revised Hata model serves as the prototype, and the coefficient in the model formula is tuned according to the data obtained in the radio propagation feature test specific to local actual radio environment, so as to obtain the propagation model for practical prediction. A common digital map only contains the clutter information and the digital terrain model information. So the building designers cannot fully allow for the influence of radio propagation, and can only estimate the influence on the building roughly from a traditional perspective, e.g., consider the influence of different clutters through certain clutter offset.

在传统的GSM网络规划中，一般都以修正的Hata模型为原型，再利用规划软件通过导入针对当地的实际无线环境做无线传播特性测试所得的数据对模型公式中的系数进行修正而得到实际预测用的传播模型，一般使用的数字地图仅包括地物信息和高程信息，因此建筑物对无线传播的影响无法充分考虑，只能从统计意义上对建筑物的影响进行粗略的估计，如通过一定的地物偏移来考虑不同地物的影响。

From the view of torque controlling strategy, the relation between the torque controlling strategy such as the electric current feedback method、 PWM open loop method etc and the vehicle driving way is analyzed firstly, then the conclusion could be drawn that the PWM open loop method has more advantages than the electric current feedback method when they are both used in the same vehicle which is direct driving by hubcap motor. Secondly, based on the electric motor mathematic model and its experiment, a new permanent brushless dc motor phase electric current detector method in which a digital signal processor and single current sensor are used is introduced.
