    摘要: Provided are a macro-diversity transmission apparatus and method for providing a broadcast/multicast service using multiple transmitting antennas in a wireless cellular communication system. The apparatus and method apply spatial multiplexing using multiple antennas within a cell and obtain additional diversity among adjacent cells or base stations. Therefore, the signal-to-interference ratio (SIR) and diversity order of signals received by terminals at cell boundaries can be increased. Consequently, cell coverage for a particular data rate can be increased, and transmission power can be reduced. Here, additional diversity applied among cells or base stations includes a method of changing antennas transmitting the same information among cells and a cyclic delay diversity (CDD) method.
