  A detection scheme for uplink massive MIMO, dubbed massive-BLAST or M-BLAST,
is proposed. The derived algorithm is an enhancement of the well-known soft
parallel interference cancellation. Using computer simulations in massive MIMO
application scenarios, M-BLAST is shown to yield a substantially better error
performance with reduced complexity, compared to the benchmark alternative of a
one-shot linear detector, as well as the original sequential V-BLAST. Hence,
M-BLAST may serve as a computationally efficient means to exploit the large
number of antennas in massive MIMO.
