Rotation block structures for MIMO LBR realizations

MIMO LBR 시스템 구현을 위한 회전 블록 구조

In this paper we propose various rotation block realization method of MIMO LBR system. For this, we first discuss how to realize a given LBR system in the form of LBR two-pair cascades. Then we examine several systematic extraction procedures which enable to realize each LBR two-pair in the form of rotation block. Then we consider which realization methods we select for each two-pair block in view of the dynamci range of the coefficients of the rotation blocks. Finally, we demonstrate the LBR realization method using a detailed numerical example that converts a 4th order IIR filter function into a 4*4 transform domain transfer matrix, and then realizes it in a rotation-block cascade.
