A mobile communication apparatus with multiple transmission and reception antennas and a mobile communication method therefore are provided. In the mobile communication apparatus including a base station and a mobile station, the base station with at least one transmission antenna restores long-term information and short-term information from a received feedback signal, spatially processes dedicated physical channel (DPCH) signals using basis information generated from the restored long-term information and short-term information, and transmits the results of adding pilot channel (PICH) signals to the spatially processed results, to the base station. The base station with at least one reception antenna determines a first characteristic corresponding to the channel downlink characteristic for each of the transmission and reception antennas using the PICH signals transmitted from the base station, determines the long-term information and short-term information based on the first characteristic, converts the determined long-term information and short-term information to a feedback signal, and transmits the feedback signal to the base station. The long-term information includes effective long-term eigenvectors and effective long-term eigenvalues, and the short-term information includes effective short-term eigenvectors and effective short-term eigenvalues. Therefore, the effects of interference and noise may be reduced, and transmission data throughput may be increased, thereby minimizing fading effects. |
