Abstract

The system has a specific number (i = 1 to I) of measuring channels, each measuring signal (x<(i)>) having a channel-independent component(s) which is weighted with a channel-dependent compensation coefficient (A<(i)>), and an additive, channel-dependent interfering component (u<(i)>). Initially, a preliminary compensation value (sum) is formed from the measuring signals and the compensation coefficients and preliminary compensated measuring signal values (sk<(i)>) are formed with said compensation value. Measuring channels (j = 1 to J) with a high degree of interference are then sought. For these channels a respective approximation value (ñ) of the interference signal is determined and used to form a correction value (@). A final compensation value (sum'), with which the final compensated measuring signal values (sk') are calculated is formed using the correction values (@).
