IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005•ieeexplore.ieee.orgThis paper deals with a multi-user downlink MIMO-OFDM scheme with perfect channel
knowledge at both the transmit and receive sides. The objective is to optimize the average
BER while fulfilling each user's rate and satisfying a global transmit power constraint. Space
division multiple access (SDMA) is investigated and three new iterative schemes are
proposed to compute the linear pre-decoders. The results exhibit, inter alia, that
orthogonalizing the channels does not lead to the best results.
