PROBLEM TO BE SOLVED: To provide an adaptive array base station and a mobile communication terminal, by which speech quality can be maintained and a calculation converging time required for extracting a user can be reduced. SOLUTION: Since a UW(Unique Word) 1 is an encoded original UW in use conventionally, in order to make UWs respectively having UW 1, UW 2 orthogonal to each other, it is required to zero the inner product shown in Equation (3). |
