Abstract

Optimal multi-antenna wideband signaling schemes are derived for multipath channels assuming perfect channel state information at the transmitter. The scheme that minimizes the bit-error-probability in the single-user case is a rank-one space-time beamformer which focuses the signal transmission in the direction of the most dominant channel mode. Several sub-optimal variations are discussed for multiuser applications. Simulation results are given to compare the schemes proposed.
