BEAM DESIGN METHOD AND ALGORITHM FOR TIME-VARYING MULTIUSER MIMO INTERFERENCE CHANNELS TRANSMITTING MULTIPLE DATA STREAMS

摘要

PURPOSE: An algorithm for multi-transmission streams in time variation multi-user multi-antenna interference channel environments and beam design method using the same are provided to simply calculate a beam formation vector by applying an adaptive beam formation calculation algorithm to a calculation process. CONSTITUTION: A fixed matrix is constituted using a channel matrix and a linear combination coefficient matrix(S20). Characteristic vectors are extracted using the constituted matrix(S30). A beam vector is constituted using the characteristic vectors(S40). The linear combination coefficient matrix is updated using the beam vector(S50). Repeated calculation factor values are increased(S60).
