Abstract
A mobile station of the mobile communication system measures signal energy on a traffic channel and interference energy on a sync channel to calculate SIR, compares the calculated SIR with a threshold, and then transmits the comparison results to a base station for a forward power control operation. To this end, a PN despreader multiplies a received signal by a unique PN code and outputs a PN despread signal. An orthogonal code despreader multiplies the PN despread signal by a sync channel orthogonal code and a traffic channel orthogonal code and outputs first and second orthogonal code despread signals. An interference energy processor measures interference energy by processing the first orthogonal code despread signal. A signal energy processor measures signal energy by processing the second orthogonal code despread signal. An SIR calculator calculates SIR depending on the measured signal energy and interference energy. The calculated SIR is compared with a predetermined threshold and the compared results are transmitted to the base station for the forward power control operation.
