  A multiuser multiple-input multiple-output wireless communication system is
analytically studied under the short-packet transmission regime. The practical
scenario of channel estimation errors is adopted when the signals undergo
Rayleigh channel fading conditions. Unlike most previous works, the channel
estimation error term is treated as a signal rather than interference or noise,
which may further enhance the overall system performance. The spatial
multiplexing mode of transmit operation is considered, while the zero-forcing
detection is applied at the receiver. New and exact closed-form expressions for
the outage probability and total system goodput are derived. Capitalizing on
the analytical results, some new engineering insights are also presented; such
as the impact of channel estimation errors with respect to the number of
antennas, transmit power, and/or coding rate.
