Abstract
An apparatus and method for power control are provided. In a receiver in a mobile communication system, a Receive (Rx) signal received through a plurality of antennas is estimated. A power ratio between a traffic channel of the Rx signal and a pilot channel of the Rx signal is determined. A Log Likelihood Ratio (LLR) value is determined using the power ratio between the traffic channel and the pilot channel, a symbol of the traffic channel, and an Rx signal estimation value to which precoding is applied.
