ICASSP 2005, 30th IEEE International Conference on Acoustics, Speech, and Signal Processing, March 18-23, 2005- Philadelphia, USA
The use of multiple transmit (TX) and receive (RX) antennas allows multiple signal streams to be transmitted in parallel and hence communication capacity to be increased. We have previously introduced simple convolutive linear precoding schemes that spread transmitted symbols in time and space, involving spatial spreading, delay diversity and possibly temporal spreading. We show that the use of the classical MIMO DFE for this system allows the optimal diversity versus multiplexing tradeoff, introduced by L. Zheng and D. Tse (see IEEE Trans. Info. Theory, vol.49, no.5, p.1073-96, 2003), to be achieved.
