The method involves defining all transmission channels within the defined transmission area. The objects are divided into homogeneous elements (Li,Lj,Lk) whose dimensions are at least a multiple of a wavelength of the signal. A spatially extended propagation channel is defined between all pairs of elements between which there is a direct signal path. Coupling coefficients are defined for channels (Zij,Zjk) with common elements (Lj). The signal transmitted by the one or more transmitters is coupled into a propagation channel which crosses the position of the transmitter. That part of the signal is defined which is transmitted to a propagation channel which crosses the position of the receiver to enable the transmission quality to be derived. |
