Recent Advances on MIMO Processing in the SATURN Project

We highlight some recent results on the theory and algorithms for MIMO systems, obtained at the Royal Institute of Technology (KTH) within the SATURN project. The paper includes a a new approximate expression for the ergodic channel capacity of a MIMO system with correlated fading, algorithms for MIMO beamforming under EIRP (equivalent isotropic radiated power) constraints and a low-complexity algorithm for MIMO channel estimation in OFDM systems. Also, we show how transmit and beamformers can be determined in a decentralized fashion without explicitly estimating the channel response.
