Traditional power control algorithin is to use a convergent iteration fimtion to set up a mathematical model . when such method is used to control the power of user , we should find the optimum solution vector of the convergent iteration funhon by iteration transform 在傳統(tǒng)的功率控制算法,通常采用某個迭代關(guān)系式為其建立某一的數(shù)學(xué)模型,該迭代關(guān)系式應(yīng)滿足收斂特性。
