It's the same problem, i.e. fitting a distance matrix using some sort of tree. I've found the five branch tree works well for four nodes. [RR] These trees are means for approximating a higher dimensional real-world problem with a lower dimensional structure. You may be doing this to save hardware when trying to cable up some complex test scenarios, however I'm wondering why? Why not just put the STAs in the lab and turn them on rather than cabling them?
