Massive BLAST: An Architecture for Realizing Ultra-High Data Rates for Large-Scale MIMO

A detection scheme for uplink massive MIMO, dubbed massive-BLAST or M-BLAST, is proposed. The derived algorithm is an enhancement of the well-celebrated soft parallel interference cancellation. Using computer simulations of practical massive MIMO application scenarios, M-BLAST is shown to render a substantially better error performance, and consequently a noticeably higher throughput, than not only the benchmark alternative of a one-shot linear detector, but also than the original sequential V-BLAST, although the latter being computationally infeasible for massive MIMO.
