Abstract
Disclosed is a MIMO-OFDM-based intercellular cooperative communication system and a cooperative communication method using the system, the system and method using the system mitigate influence of an intercellular interference and to increase reliability of the mobile terminal located at an edge of a cell, using a CoMP scheme by which base stations cooperate in a HetNet system, a pre-coding scheme by which a channel coefficient of a desired signal increases and a channel coefficient of an interference signal is reduced, and a MIMO detection scheme with an excellent signal detection performance.
