ADAPTIVE BEAM TRACKING FOR INTERFERENCE ALIGNMENT IN TIME-VARYING MIMO INTERFERENCE CHANNELS: CONJUGATE GRADIENT APPROACH

摘要

PURPOSE: An adaptive beam design method and an access method are provided to generate a new beam vector based on information about a current channel and a previously calculated beam vector. CONSTITUTION: A cohesion coefficient matrixes Akl is updated(S10). The size of a matrix consists of a channel matrix Hk1 and a liner combination coefficient matrix Akl(S30). An eigen vector is extracted through a matrix(S40). The eigen vector of the smallest R is extracted by using an algorithm 1(S50). Time(n) is varied(S60).
