A study of unequal power control in ATM/CDMA wireless communication networks

An analysis of "unequal power control (UPC)" for the general integrated services is presented based on our former discussion about UPC for voice/data integrated services. This optimal control problem is clarified first, and then an approximate solution is derived by linear programming. For practical application, we propose an implementation scheme based on simulation. Numerical results show that unequal power control can expand the "allowable load area" and provide a significant improvement in system capacity comparing with equal power control.
