Signal receiving method and apparatus in a multiple access system using a multi-carrier

The present invention includes the steps of receiving a signal containing the base station identification information from at least one base station, and performing channel estimation (Channel Estimation) for each base station using the signal, using the channel estimation information, signal receiving method in the step of combining the signals transmitted from each base station and the multiple access method using the multi-carrier comprising the step of decoding the combined signal system, and relates to a receiving apparatus using the same, multi-carrier multiple access in the mobile communication system using the technology, the mobile station being handed over there is an effect that allows decoding by combining the received signal more efficiently.
