But above all, the (multi-channel) BAF performs spatial filtering, which mainly affects the interfering point sources.
Figure 10 illustrates the magnitude responses of Directional BSS steering at 0°, with one interfering point source at 30°.
One of the point sources may be seen as the target source to be extracted, the remaining being considered as interfering point sources.
For simplicity and without loss of generality, we assume that there are two interfering point targets, one moving and one stationary.
The minimum feedback needed for interference coordination is the precoder that causes the worst interference if used at the interfering point.
Ideally, the BSS filters should converge to a solution which minimizes the contribution of the interfering point sources at the BSS output, that is, (70).

We consider a network composed of two interfering point-to-point links where the two transmitters can exploit one common relay node to improve their individual transmission rate.
Interfering points are transmitting using random ranks and PMIs.
The amplitude of the interference will be proportional to the double product of the amplitudes of the interfering points.
In these simulations, UEs are allowed to connect to center site points only, and points located in the rest of the sites are considered as interfering points.
This is done to achieve a realistic UE placement so that the examined UEs are surrounded by interfering points, which is the case in real networks.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
