It is known that in cellular systems, the users in cell edge suffer from the interference from interfering cells. In LTEA, Coordinated Multi-Point (CoMP) processing was proposed to solve the problem. In CoMP, the transmitted/received signals of the users in neighbor cells can be jointly processed such that interference can be either avoided or estimated as desired signals. In the current CoMP operations, precoding is only conducted between individual base-stations and the served user. If the authors take all the base-stations and the served user into consideration, a network Multiple-Input-Multiple-Output (MIMO) system can be constructed.
