Abstract

In this paper, new space-time coding schemes for multiple transmit and receive antenna systems (MIMO) are proposed. By applying a specific block coding scheme for transmission, the MIMO channel is structured in an advantageous manner. Diversity can be gained simultaneously with savings in receiver complexity. In a second step, such structured schemes and BLAST schemes are combined, offering and continuous trade-off between quality of service (QoS) and choice of data rate. Due to the simplicity of the coding schemes, only very moderate modifications in the existing UMTS standard are required in order to support them. If the transmitter knows the numbers of antenna elements at both sides of the radio link then this is sufficient for selecting the most appropriate scheme.
