Such schemes can be termed transmitter Tx oriented and have the potential of simple transmitter implementations. The opposite to Tx orientation would be receiver Rx orientation in which the receiver algorithms are a priori given and the transmitter algorithms have to be a posteriori adapted. An advantage of the rationale Rx orientation is the possibility to arrive at simple receiver structures. In this paper linear versions of the rationales Tx orientation and Rx orientation are applied to radio transmission systems with multiantennas both at the transmitter and receiver. After the introduction of adequate models for such multiple-input multiple-output MIMO systems different system designs are evaluated by simulations and recommendations for proper system solutions are given. Keywords and phrases MIMO systems transmitter orientation receiver orientation. 1. INTRODUCTION In conventional transmission schemes the transmitter algorithms are a priori given and made known to the receiver whereas the algorithms to be used by the receivers have to be a posteriori adapted possibly under consideration of channel information. For this approach
