Abstract

Systems and methods for maintaining base stations are provided. In this regard, a representative system, among others, includes a base station that is configured to receive transmitted signals from one or more mobile stations, calculate one or more data rates based on the transmitted signal associated with the one or more mobile stations, respectively, and generate data rate signals based on the calculated one or more data rates. The base station includes a dithering unit that is configured to apply dithering noise to the data rate signals, and memory that includes channel assignment logic configured to assign access channels to the one or more mobile stations based on the dithered signals, respectively.
