Abstract :
The proposed singular value decomposition (SVD) aided spatial multiplexing (SM) based multiple-input-multiple-output (MIMO) system is capable of achieving a high bandwidth efficiency. The SVD operation effectively splits the MIMO channel into orthogonal eigen-beams having unequal bit-error-ratios (BERs). This property may be exploited for the transmission of speech, audio, video and other multimedia source signals, where the source-coded bits have different error sensitivity.
