1.An implicit assumption in our discussion is that the power levels of all stations are the same as perceived by the receiver.
1.在我們的討論中隱含著一個(gè)假設(shè)是，所有基站的功率水平在接收器看來(lái)都是一樣的。

2.CDMA it typically used for wireless systems with a fixed base station and many mobile stations at varying distances from it.
2.CDMA通常用于無(wú)線系統(tǒng)，系統(tǒng)中包含一個(gè)固定站和許多與它距離不同的移動(dòng)站。

3.The power levels received at the base station depend on how far away the transmitters are.
3.基站收到的功率水平取決于發(fā)射機(jī)與它的距離。

4.A good heuristic here is for each mobile station to transmit to the base station at the inverse of the power level it receives from the base station. In other words, a mobile station receiving a weak signal from the base station will use more power than one getting a strong signal. The base station can also give explicit commands to the mobile stations to increase or decrease their transmission power.
4.這里有一個(gè)很好的啟發(fā)，對(duì)于每個(gè)移動(dòng)站來(lái)說(shuō)，它們所發(fā)射到基站的功率與它們從基站接收到的功率相反。換句話說(shuō)，一個(gè)從基站收到弱信號(hào)的移動(dòng)臺(tái)，將比一個(gè)收到強(qiáng)信號(hào)的移動(dòng)臺(tái)發(fā)射更高的功率。基站還可以向移動(dòng)臺(tái)發(fā)送明確的指令，讓它們?cè)黾踊蛘邷p少其發(fā)射功率。

5.Ideally, the component should be removed from the circuit completely; but if this is inconvenient (at least until if proves necessary for removal), one or more leads should be disconnected and care taken to avoid current paths in neighboring components when testing.
5.理想的方法是把該元件從線路中完整取出。但如果不方便的話（至少要在判別需要去掉之前），應(yīng)該斷開(kāi)一根或幾根引線，應(yīng)當(dāng)避免在測(cè)試時(shí)鄰近的元件之間有電流通路。
