Abstract: In the realm of CDMA cellular communication systems, effective power control stands out as a critical resource management strategy. Its implementation is imperative to ensure that each user transmits at the minimum necessary power, thereby optimizing network capacity. The primary culprits hindering capacity are the interferences stemming from co-channel and adjacent-channel sources. Various power control algorithms play a pivotal role in regulating transmission power levels. The objective is to employ these algorithms to guarantee the desired quality of service for users while utilizing the lowest feasible transmission powers. This paper undertakes a comparative analysis of the evolutionary progression of diverse power control algorithms within the context of third-generation WCDMA systems.
