NDLI: Asymptotic analysis of two-layer D-BLAST with group-zero forcing detection in general channels

Abstract	In this study, the authors perform the asymptotic analysis of two-layer D-BLAST transmission scheme with group detection receiver under broad class of fading channels. The asymptotic analysis includes both diversity-multiplexing trade-off (DMT) and throughput-reliability trade-off (TRT) analyses. The D-BLAST considered here is a multi-layered space–time transmission scheme, wherein each diagonal of code-word forms a group. On the other hand, group detection considered detects symbols by nulling out interference from other groups and performs maximum-likelihood decoding on the chosen group. The reason for choosing this scheme is that the first inflexion of DMT of this system ceases at multiplexing gain ≪1, i.e. second inflexion began at multiplexing gain <1 under Gaussian fading scenario. The results of DMT indicate that the system behaves differently in different fading channel constraints when multiplexing gain ≪1. The results of the TRT analysis show that the system performs different in different fading channels in the zeroth operating region.
