Abstract
A multi-user system includes radio channels which are independent and uncorrelated for different users. The system operates with frequencies which, due to multi-path propagation, are more or less attenuated for one user and more or less amplified for another user. Elements are arranged to detect or measure the attenuation/amplification for the different frequencies. The elements also prevent signal or information transmission at frequencies which drop below a predetermined lowest attenuation by disconnecting the frequency or frequencies in question and connecting a corresponding number of frequencies which pass the attenuation value criterion.
