PRE-CODING METHOD, PRE-DECODING METHOD, TRANSMITTER AND MOBILE TERMINAL BASED ON INTERFERENCE ALIGNMENT |
摘要 |
The transmitter and a mobile terminal based on interference alignment use pre-coding and pre-decoding methods. An antenna mapping matrix is computed according to a downlink channel state information, wherein the antenna mapping matrix is used for antenna mapping for the current transmitter to perform interference alignment. A multi-cell pre-coding matrix according to the downlink channel state information and the antenna mapping matrix; a single cell multi-user pre-coding matrix and pre-coding user data using the single cell multi-user pre-coding matrix and the multi-cell pre-decoding matrix and performing an antenna mapping using the antenna mapping matrix are computed. A system which cannot use the interference alignment method directly may be transformed to use the interference alignment method directly. In addition, the interference suppression between cells and the interference management inside cells are two separate processes, in which different linear pre-coding and decoding methods may be used.
