Which of the following is the correct statement of MIMO technology gain? (Multiple choice)
A . Multiplex gain obtain the throughput gain by increasing the number of spatial channels.
B . Diversity gain is a performance gain obtained by reducing the fading amplitude of the combined signal (ie, the variance of the signal-to-noise ratio) with respect to the SISO channel of a single antenna system, with a lower probability that the MIMO channel experiences deep fading at the same time.
C . Interference cancellation gain achieves an optimal balance between minimizing the interference gain and maximizing the signal gain, thereby maximizing the SINR of the combined signal
D . Modulation gain use higher modulation, which can increase the rate
