Description: MU-MIMO is widely considered a key technology
for system capacity improvement in modern
wireless networks. In contrast to
SU-MIMO, where the spatial multiplexing gain
is confined to a single user, MU-MIMO allows
multiple users to be co-scheduled on the same
time-frequency resources to exploit this gain
among two or more UE units. This is particularly
beneficial as high-rank SU-MIMO transmission
is often limited by the number of
antennas and antenna design constraints at the
user end, whereas high-rank transmission using
MU-MIMO is more feasible due to the scattered
user distribution.
It is well known that the information theoretic
optimal MU-MIMO scheme is dirty paper
coding (DPC), which unfortunately is a nonlinear/
non-causal beamforming scheme and therefore
unrealistic in real-life applications. From a
practical deployment point of view, the most Platform: |

Description: MIMO系统由于在空间中具有多个发送和接收天线，因此其信道模型也具有其特有的复杂性。尽管具有这种复杂性，对MIMO信道进行建模仍然十分必要。因为在MIMO传输技术的研发过程中，需要对新技术进行链路级或系统级的仿真，以此评估各种传输技术的实际性能。而只有对MIMO信道进行了足够精确的建模，并将信道模型应用在计算机仿真中，才能进行贴近实际的性能评估，得出有参考价值的评估结果，为传输技术的研发指明正确的道路。(MIMO system has multiple transmit and receive antennas in space, so its channel model has its own complexity. Despite this complexity, it is necessary to model MIMO channel. Because in the development of MIMO transmission technology, it is necessary to simulate the new technology at link level or system level to evaluate the actual performance of various transmission technologies. Only by modeling the MIMO channel accurately enough and applying the channel model to computer simulation, can we evaluate the performance close to the actual situation and get the valuable evaluation results, which will point out the right way for the development of transmission technology.)
