Advanced DL MU-MIMO precoding (Null-Space Projection)

Presented by Dr. Doron Ezri, CTO Wi-Fi at Huawei’s Tel-Aviv Research Center

Agenda

DL MU-MIMO plays an important role in modern wireless communications: e.g., 5G and Wi-Fi 6.

It is the only way to linearly increase the rate (number of spatial streams) when the number of Tx antennas is increased.
In this talk we will discuss the essentials of DL MU-MIMO and explain why it is so important through the perspective of SU
and MU MIMO channels. We will also present some simple precoding schemes.
In the case of multiple streams per receiver, we will present the popular schemes inWi-Fi 6, and present a new scheme:

“Null-Space Projection”, which significantly outperforms the popular schemes by up to
a huge gap of 11dB!

The event will take place at INTERLLIGENT Tel Aviv Training Centre, 2 Koyfman st.

Attendance is free, upon availability.
