It employs an anechoic chamber with two test antennas that are positionable in a [THETA]-plane and a turntable for UE placement that is turnable in the [PHI]-plane, as depicted in Figure 2.
Compared with conventional kernels and with implicit kernel mapping, the nonlinear mapping of the quasi-linear kernel is turnable by M, which also reflects the nonlinearity of the quasi-ARX RBFN models in the sense of the number of local linear subspaces utilized.
