Patent ID: 8593984

Claim:
An apparatus for measuring a receiving power of each of a plurality of transmitters in a wireless communication system, comprising: a total receiving power measuring unit for measuring a total receiving power from the plurality of transmitters; an identification signal analyzing unit for extracting a channel profile signal from a signal having multi-path characteristics transmitted from one of the plurality of transmitters through multiple paths, wherein the signal includes an identification signal, and wherein the identification signal analyzing unit includes a receiving unit for receiving and converting radio frequency signals into a signal of a requested band, converting the signal of the requested band into a digital signal, and demodulating and storing the digital signal, wherein the identification signal allocated to each of the plurality of transmitters is inserted into the radio frequency signals, an identification signal generating unit for generating an identification signal identical to the identification signal allocated to each of the plurality of transmitters, a partial correlation unit for calculating a correlation value between the stored digital signal and the generated identification signal through a partial correlation scheme, a correlation value compensating unit for compensating an isolation and an attenuation of the multi-path signal using a 90°-inverted value for the correlation value calculated by the partial correlation unit, and a channel profile extracting unit for extracting the channel profile signal of the multi-path signal of each of the plurality of transmitters from a value resulting from the compensation, and an individual receiving power calculating unit for calculating an individual receiving power from the one of the plurality of transmitters based on the measured total receiving power and the extracted channel profile signal.
