In this paper, the authors present a new beamforming technique using Singular Value Decomposition (SVD) for closed loop Multiple-Input, Multiple-Output (MIMO) wireless systems with various modulation techniques such as BPSK, 16-QAM, 16-PSK, DPSK and PAM along with convolution encoder. The channel matrix is decomposed into a number of independent orthogonal modes of excitation, which refer to as Eigen modes of the channel. Transmit precoding is performed by multiplying the input symbols with unitary matrix to produce the transmit beamforming, and the pre-coded symbols are transmitted over Rayleigh fading channel.
