This paper is aimed to evaluate different distributed power control algorithms for code division multiple access (CDMA) systems. The evaluation scenarios consider three practical aspects: i) time-varying channels, ii) feedback time-delays, and iii) uncertainty in the measurement of the signal to interference-noise ratio (SINR). First, dynamic power control is formulated in its general form as a tracking problem for an objective SINR and by assuming a feedback structure. Next, seven distributed… CONTINUE READING
