Abstract:
Double codebook-based multi-user, a multi-antenna transmission apparatus and a transmission method are started. A transmission apparatus includes an effective channel information reception unit configured to receive an effective channel matrix for a transmission channel, a zero-forcing precoding unit configured to receive data streams and perform zero-forcing precoding to null inter-user interference based on the effective channel matrix, a beam forming unit configured to receive the data streams subjected to the zero-forcing precoding from the zero-forcing precoding unit and perform beam forming, and a multi-antenna array configured to transmit the data streams subjected to the beam forming by the beam forming unit to the multi-user. With the method and apparatus, it is possible to improve a transmission capacity and effectively process an interference between terminals in a multi-layer beam forming environment.
