| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the downlink (broadcast channel) of the multiuser MIMO system, suppression of inter-user interference (IUI) is an important issue to be solved. Due to the limitated antenna resources, it is difficult to implement the IUI cancellation at the terminal side. Thus, reduction of undesired radiation by a certain beam-control is preferable. The imperfect block diagonalization (IBD) has been proposed previously as one of the solutions. In the paper, we extend the IBD to be capable of multi-stream transmission per user and evaluate the BER performance using computer simulations. | |
