| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Dirty Paper Coding (DPC) is the best known interference cancellation strategy in wireless channels with additive interference, when side information about the latter is non-causally available to the transmitter. Extending the DPC interference cancellation approach to the multiple-input multiple-output (MIMO) case is challenging owing to the \textit{reciprocal} nature of cross-antenna interference. Tomlinson-Harashima Precoding (THP) is a DPC implementation in MIMO systems where the above challenge is mitigated through an LQ factorization of the channel matrix. Such matrix factorization transforms the channel gain matrix into a lower-triangular matrix, thereby taking away the reciprocal nature of the cross-antenna interference and making the interference pre-cancellable at the transmitter in a successive manner. Unfortunately, such factorization requires the knowledge of the whole channel matrix which has to be fed back from the transmitter. Such feedback signaling cost, together with the non-negligible computational cost of the LQ factorization, has prohibited THP from being applied in practice. In this work, a novel implementation of THP is presented where the LQ factorization procedure is removed. It is found that the proposed LQ-less THP implementation achieves the same performance of the conventional LQ-based THP implementation while only requiring half the CSI feedback signaling cost and two-thirds the computational complexity. The proposed implementation is of particular usefulness in deployments where the MIMO transmitter is equipped with a large number of antennas, such as the recent Massive MIMO. | |
