"Transceiver Optimization for Multiuser MIMO Systems"
by S. Serbetli and A. Yener,
in IEEE Transactions on Signal Processing, vol. 52, no. 1, January 2004, pp. 214-216

We consider multiuser wireless transmissions with multiple transmit antennas and multiple receive antennas. Every user multiplexes its symbols through its own linear precoder before being transmitted. In order to enhance the system performance by a system-level mean squared error rule, we propose algorithms to jointly optimize the linear precoders at each transmitter and linear decoders at each receiver Simulation results show that our novel algorithm has a faster convergence speed.
