On the capacity achieving covariance matrix for Rician MIMO channels: an asymptotic approach
Julien Dumont, W. Hachem, Samson Lasaulce +2
The capacity-achieving input covariance matrices for coherent block-fading correlated MIMO Rician channels are determined. In this case, no closed-form expressions for the eigenvec…

Upper bound of loss probability in an OFDMA system with randomly located users
Laurent Decreusefond, Eduardo Ferraz, Philippe Martins
For OFDMA systems, we find a rough but easily computed upper bound for the probability of loosing communications by insufficient number of sub-channels on downlink. We consider as…
