This paper presents a technique for Antenna beam forming in high data rate OFDM-MIMO systems. The technique makes use of the Singular Value Decomposition (SVD) algorithm for matrix decomposition using Givens Rotation. In this paper a hardware oriented two-step diagonalization SVD scheme is derived from simple two-sided unitary transformations developed to ensure hardware and performance efficiency using CORDIC. Each unitary transformation step in the diagonalization procedure is identical in structure to permit pipelined systolic execution. The simulation results are obtained for fixed point models using SVD algorithm. An overall architecture is created in Matlab for 4X4 Complex valued matrices elements and then simulated.
