Beam Design Algorithm In Multi-Input Multi-Output Interference Channels based on Mean Square Error and using Method thereof

摘要

PURPOSE: A beam design algorithm in an MIMO(Multiple Input Multiple Output) interference channel based on MSE(Mean Square Error) and method using the same are provided to realize low performance reduction by optimizing the MSE. CONSTITUTION: A signal received by each reception apparatus is displayed as mathematics in one or more transmission apparatuses(S10). When incomplete channel information exists in an interference channel, a modeling process is executed in order to equalize feedback errors(S20). A filter of the reception apparatus is applied to a reception signal in order to estimate an original signal(S30). A new type is created by applying an optimization method to the filter in order to consider MSE(S40).
