Multiple-input, multiple-output (MIMO) technology offers many benefits for wireless communications by leveraging multiple antennas at both the source (transmitter) and destination (receiver). With the use of MIMO, multiple streams of data can be delivered simultaneously and transmit-and-receive diversity can be fostered.

Among the most powerful improvements enabled by MIMO is the ability to use precoding to "steer" the transmitted signals. One implementation of precoding, Beamforming, focuses the signal, leading to greater signal strength at the receiver. In another implementation of precoding, known as MU-MIMO (Multi-User MIMO), a single transmitter can send multiple data streams to multiple receivers without mutual interference between the different streams. In this case, precoding achieves the desired interference cancellation by steering parts of the signal away from an intended location.

In this webinar, we will discuss the different uses of precoding and highlight the importance of high-quality channel feedback to enable precoding. We will also present use cases in which maximum user performance can only be achieved by deploying MU-MIMO.
