SU-MIMO

(Single User-MIMO) A multi-transmitter/receiver technology (MIMO) that allocates the full bandwidth of the access point (AP) to a single high-speed device during the allotted time slice. Contrast with MU-MIMO. See MIMO.

However, the SU-MIMO cannot make full use of spatial multiplexing so that it becomes a major obstacle to achieve higher data transmission rate.
Therefore, the conventional MIMO systems such as the SU-MIMO and MU-MIMO system don't have proportionally high throughput in according to the number of antenna.
MU-MIMO offers two significant advantages compared to SU-MIMO.
In addition to the general CSMA/CA MAC features, the proposed protocol acts as a switching entity between MU-MIMO and multiple SU-MIMO (mSU-MIMO) transmissions, in which mSU-MIMO includes multiple point-to-point MIMO communications during a single transmission opportunity (i.
Section 2 presents background information about CSMA/CA, SU-MIMO, and MU-MIMO, and Section 3 then describes related research.
SU-MIMO is a point-to-point MIMO communication technique.
Another observation can be drawn from Chen's scheme by comparing the performance of the suggested method, which is the zero-forcing multi-user MIMO CQI estimation with SINR approximation method in [7]-[9], and the response to the basic method of SU-MIMO as shown in Fig.
