Perform transmit and receive processing for an IEEE 802.11ac multi-user downlink transmission over a fading channel.

Double-IRS Assisted Multi-User MIMO: Cooperative Passive Beamforming Design Abstract: Intelligent reflecting surface (IRS) has emerged as an enabling technology to achieve smart and reconfigurable wireless communication environment cost-effectively. MIMO systems have already been employed in the existing 802.11n and 802.16e standards resulting in a huge leap in their achievable rates. A relatively recent idea of extending the benefits of MIMO systems to multi-user scenarios seems promising in the context of achieving high data rates envisioned for future cellular standards after 3G.

An easy observation we can make is that this uplink is very similar to the MIMO point-to-point channel in Chapter 5 except that the signals sent Figure 10.1 The uplink with single transmit antenna at each user and multiple Perform transmit and receive processing for an IEEE 802.11ac multi-user downlink transmission over a fading channel.

Multi-user MIMO (MU-MIMO) is not a new technology, but the basic concept of using multi-antenna base stations (BSs) to serve a multitude of users has been around since the late 1980s. An example of how MU-MIMO was illustrated prior to Massive MIMO. I sometimes get the question “Isn’t Massive MIMO just MU-MIMO with more antennas?” Multiple-input multiple-output, or MIMO, is a radio communications technology or RF technology that is being mentioned and used in many new technologies these days. Wi-Fi, LTE; Long Term Evolution, and many other radio, wireless and RF technologies are using the new MIMO wireless technology to provide increased link capacity and spectral efficiency MU-MIMO står för Multiple-User MIMO, och som namnet kanske antyder så är MU-MIMO en utökning av SU-MIMO standarden som låter enheter med MIMO stöd prata samtidigt med flera andra trådlösa enheter. MU-MIMO används i nyare 802.11ac enheter, men man måste känna till att 802.11ac i sig inte garanterar att enheten har stöd för MU-MIMO.

Multi-user MIMO technology (MU-MIMO) works on 5 GHz 802.11ac Wi-Fi networks. Whereas SU-MIMO requires routers to manage client connections serially, one client at a time, MU-MIMO antennas manage connections with several clients in parallel. MU-MIMO improves the performance of connections that are able to take advantage of it.

It allowed the router to transmit at faster speeds by sending data through multiple antennas. This has now evolved from the original Single-User MIMO (where the router can “talk” to only one device at a time) to Multi-User MIMO (where the router can “talk” to multiple devices at the same time). Multi-User MIMO in WiFi 6 Multi-User MIMO (MU-MIMO) is one of the key features of WiFi 6. While Single-User MIMO (SU-MIMO) results in scaling of per-user throughput as a result of multi-stream transmission, its benefits are somewhat limited by the fact that most clients support either 1 or 2 spatial streams. MU-MIMO(multi-user MIMO, 다중 사용자 MIMO)는 제각기 하나 이상의 안테나를 갖춘 사용자나 무선 터미널들이 서로 통신하는, 무선 통신을 위한 MIMO 기술들의 집합이다. Multiple User MIMO Communication.

As shown two streams are directed to one device(nokia mobile) and other streams one to one device(tablet) and the other one to another device(laptop).This is referred as Single user MIMO, Multi user MIMO also referred as MU-MIMO. Multi-user MIMO multiplexing and spatial diversity are indispensable techniques to improve the link capacity in a fading environment. In this paper, user-wise joint transmit-receive diversity Multi-user MIMO allows multiple Wi-Fi devices to simultaneously receive multiple data streams.

MU-MIMO, Multi-user MIMO enables multiple independent radio terminals to access a system enhancing the communication capabilities of each individual terminal. Accordingly it is often considered as an extension of Space Division Multiple Access, SDMA.
