ABSTRACT:
Method and apparatus for measuring the quality of the radio transmission channels during the transmission in progress, and for recording co-channel interferences, fast fluctuations caused by interferences are separated from slow fluctuations caused by fading, are measured and a quality indicator is derived from the test values of fast and slow fluctuations. By means of the separate measurement of the sum of the power of the receiver input noise and the power of co-channel noise sources it is possible to effect in a simple way and manner a selection of the stationary station having the best receiving condition.
