We propose a novel control method for an unknown distributed system, and apply it to transmission power control in a code-division multiple access (CDMA) wireless system. Our proposed distributed control contains conventional transmission power control and packet transmission rate control for constant bit rate (CBR) and transmission control protocol (TCP) connections. Using theoretical analysis and computer simulations we show that our method for transmission power control allows high bandwidth utilization for both CBR and TCP connections, and that conventional power control, by contrast, does not make efficient use of bandwidth in TCP connections.
