Abstract
Next generation wireless networks are mainly designed to support intermittent packetized data traffic. This situation raises the question of how to do power control for information sources other than voice. To explore this issue, we utilize the delay insensitive property of the data traffic to transmit packets when the channel condition is good and stop transmission when the channel condition is bad. An algorithm is proposed to control the transmission power based on signal-to-interference ratio estimation in a code-division multiple-access (CDMA) mobile radio system under multipalh environment. Simulation results show that significant performance improvement has been achieved.
