Power Control for Wireless Cellular Systems Via D.C. Programming

Power control at the base station is typically used in wireless cellular networks in order to optimize the transmission subject to Quality of Service (QoS) constraints. It has been shown that the power control problem in the wireless cellular network framework can be efficiently solved using the so called geometric programming. However, in order to enable the application of geometric programming the Signal to Interference Ratio (SIR) has been considered instead of Signal to Interference plus Noise Ratio (SINR).
