Paper Abstract

The combination of adaptive modulation (AM) at physical layer and truncated automatic repeat request at data link layer in V-BLAST system is considered in this paper. We deduce the spectral efficiency and the outage probability from our proposed design over frequency-flat Rayleigh channels in presence of transmit correlation. Numerical results reveal that the joint design of AM and truncated ARQ in V-BLAST system can achieve considerable spectral efficiency gain and outage probability reduction.
