Linear transmit processing in MIMO communications systems
TL;DR: The transmit filters are based on similar optimizations as the respective receive filters with an additional constraint for the transmit power and has similar convergence properties as the receive Wiener filter, i.e., it converges to the matched filter and the zero-forcing filter for low and high signal-to-noise ratio, respectively.
Proceedings ArticleDOI
Minimum Mean Squared Error interference alignment
TL;DR: Numerical results are presented, which show that this method achieves interference alignment at high SNRs, and can achieve different points on the boundary of the achievable rate region by adjusting the MSE weights.
Journal ArticleDOI
Learning the MMSE Channel Estimator
TL;DR: A method for estimating conditionally Gaussian random vectors with random covariance matrices, which uses techniques from the field of machine learning to obtain a similarly efficient (but suboptimal) estimator).
Proceedings ArticleDOI
Transmit Wiener filter for the downlink of TDDDS-CDMA systems
TL;DR: The transmit Wiener filter for DS-CDMA systems shows that it converges to the transmit matched filter and the transmit zero-forcing filter for low and high signal-to-noise-ratio, respectively.
Journal ArticleDOI
Fading correlations in wireless MIMO communication systems
TL;DR: It will be shown, that in some cases correlated fading may offer better performance than uncorrelated fading permits, which is due to exploitable antenna gain, that will also be defined in a general form for MIMO systems.
