Coverage map with/without beamforming

[Advaith2212]

Hello,

I wanted to see the variation of coverage map with and without the effect of beamforming in Sionna RT.
1. For a given scene, the transmitter and receiver were initially placed.
2. Initially, the coverage map is computed and using SVD, the precoding vec has been found out.
3. The computed precoding_vec is passed as an argument to the cm function to see the effect of beamforming in coverage map.

In both the instances, they appear to be similar. Can you help me with this.

Hi,

First of all, as soon as you have a transmitter with multiple antennas, precoding is assumed for the computation of the coverage map (as it would not be defined otherwise). Please check the API documentation.

Second, it is probably not very useful to compute the precoding vector based on the SVD of a particular channel realization in this case. One would rather pick a precoding vector that points toward a specific direction.

Third, could you share a code snippet that reproduces your results?
