Recent theoretical and experimental studies have shown that with affordable complexity, layered space-time (LST) transmissions can attain very high spectral efficiency in a rich-scattering environment. In this paper, we propose a novel high rate linearly precoded LST system, which allows for any number of transmit and receive antennas, and offers flexibility in trading performance with bandwidth efficiency and decoding complexity. Even with sub-optimum decoding, the system enjoys considerable transmit diversity gains. Its superior performance over existing uncoded V-BLAST and linear dispersion (LD) codes is confirmed by simulations.
