Abstract

The concatenation scheme MLC-STBC combining multilevel codes (MLC) and space-time block codes (STBC) is proposed over Rayleigh fading channels. Through performance analysis and computer simulation, the asymptotic behavior of the new system is provided, which is proportional to the product of the space diversity and the minimum Hamming distance of the component codes. The simulation results show that, with the same bandwidth efficiency, the concatenation scheme has better power efficiency than the MLC system. Considering the fact that multistage decoding (MSD) and parallel decoding on levels (PDL) have a little difference in the system performance, the concatenation scheme MLC-STBC with PDL decoding method (MLC-STBC/PDL) achieves better trade-off between performance and complexity.
