Abstract :
A novel LST architecture that outperforms the performance of V-BLAST, in the presence of channel estimation errors at the receiver, is proposed. Multiplexing gain is traded-off by transmitting known symbols from one of the transmit antennas, which allows an enhancement in diversity due to an improved interference suppression.
