$3\mathrm{.}2$ Performance comparison between massive MIMO and traditional MIMO

In $3$GPP$,$ MIMO technology generally evolves along the development of single$-$user MIMO, multi$-$

user MIMO and network MIMO. Compared with traditional MIMO technology, the performance of

massive MIMO technology is reflected in many aspects. The performance comparison between

traditional MIMO and massive MIMO is presented in table $2.$
