SUBSPACE INTERFERENCE ALIGNMENT METHOD

摘要

PURPOSE: A subspace interference sort method thereof is provided to prevent a difference error with an estimation channel by time-changing a real channel, an error of and channel errors that are occurred during decomposition. CONSTITUTION: A separate unit separates a channel through channel with a base station of a channel of a cell in which a mobile station belongs and an adjacent cell(S301). A first setting unit establishes a reference vector that is especially used the cell as an orthogonal vector(S302). A second setting unit establishes a transmission vector corresponding to a mobile station by using the reference vector(S303). A signal transmission part transmits signal by using the transmission vector. A received vector sorts the subspaces that is included to an interference signal by using the received vector(S306).
