  This paper investigates the distributed space-time (ST) coding proposals for
the future Digital Video Broadcasting--Next Generation Handheld (DVB-NGH)
standard. We first theoretically show that the distributed MIMO scheme is the
best broadcasting scenario in terms of channel capacity. Consequently we
evaluate the performance of several ST coding proposals for DVB-NGH with
practical system specifications and channel conditions. Simulation results
demonstrate that the 3D code is the best ST coding solution for broadcasting in
the distributed MIMO scenario.
