Chapter 8 Power Control

Power control is crucial to the operation of CDMA systems. As the channel path loss varies due to mobile station movement, the mobile station’s and base station’s traffic channel transmit power must be changed accordingly to ensure that the received signal strength is equal to the receiver’s sensitivity, that is, the level required for reliable signal demodulation. If the transmit power is not increased in response to an increase of path loss, the received signal power will fall below receiver sensitivity, thus degrading quality of service (QoS). Conversely, if the transmit power is not decreased in response to a decrease of path loss, the received signal power will exceed the receiver sensitivity, thus creating excessive ...
