Abstract :
The BLAST architecture provides a physical layer transmission technique that achieves very high spectral efficiencies in rich scattering environments using multiple transmit and multiple receive antennas. We perform a system performance evaluation in term of spectral efficiency where BLAST and hybrid ARQ are combined together. While the previous work is focused on Rayleigh fading channels, we extend it to a general wireless environment with different level of scattering
