A novel Lattice Precoding scheme based on Eigenvalue decomposition (EDLP) is proposed for single user multiple- input multiple-output (MIMO) communication systems transmitting over slowly-varying flat-fading channels. This technique uses linear precoding to orthogonalize the channels, thus nullifying the interference. It employs a perturbation vector as well to reduce the transmitted power. The performance...
This paper provides some details of a novel vector perturbation based lattice precoding algorithm based on Eigenvalue decomposition, named EDLP, for single user multiple-input multiple-output (MIMO) systems operating over slowly-varying flat-fading channels. Linear precoding is used in this technique to orthogonalize the fading channel, thus nullifying the interference among spatial channels. A perturbation...
A novel Coordinated Interference-aware Beamforming (CIB) technique for Multiple-Input-Multiple-Output (MIMO) Broadcast Channels (BC) is introduced. The CIB technique uses a method based on maximization of the Signal to Interference and Noise Ratio (SINR) at the front end of each receiver to balance the signal strength and the multi-user interference plus noise. This results in a closed form solution...
In this paper a linear multi-user beamforming technique is proposed for frequency-selective channels in multiple-input-multiple-output (MIMO) wideband code division multiple access (WCDMA) system. Assuming perfect Channel State Information (CSI) is available at both transmitter and receiver, transmit beamforming and receive beamforming are coordinated to mitigate multi-user, multiple access (MAI),...
We propose a novel linear transmit beamforming technique for multi-user MIMO broadcast channels (BC). We lower bound the product of all users' received SINRs when MMSE receivers are employed by all users. The proposed closed-form solution for transmit beamforming maximizes the lower bound of the product SINRs in an autonomic way. Unlike the zero-forcing beamforming (ZFBF), which can completely cancel...
