Abstract
Multiple-input multiple-output (MIMO) using orthogonal frequency division multiplexing (OFDM) technique can be considered as a key technology in the recent high data rate wirless communication systems. there are many scemes that can be applied separately to MIMO-OFDM sYSTEMS IN order TO ENHANCE DATA TATE OR SER PERFORMANCE SUCH AS SPACE-TIME BLOCK coding (STBC), singular value decomposition (SVD) and the vertical bell labs layered space-time architecture (VBLAST).
