Abstract:
1. A reception apparatus for receiving a plurality of different data streams in a multiple input multiple output (MIMO) antenna system, comprising: a data stream detector for detecting each data stream by removing interference between the different data streams while maintaining channel information; and a cochannel interference (CCI) remover for removing cochannel interference from each data stream detected in the data stream detector; wherein the plurality of different data streams are transmitted from transmission antennas divided into antenna groups; wherein the data stream detector detects a first data stream transmitted from a lowermost antenna group among the antenna groups, then detects a second data stream transmitted from a next antenna group of the lowermost antenna group, by eliminating the first data stream in the second data stream; wherein each data stream is received through an independent channel which is formed between each antenna group and the reception apparatus; wherein each data stream is transmitted from a corresponding one of the antenna groups through a corresponding independent channel.
