The invention relates to a digital radio link system and a method of adjusting the transmission power in a digital radio link system. The system comprises at a receiving end (2) a first means (11) for monitoring the error rate estimate and for producing a first control signal (Serr) if the error rate estimate exceeds a predetermined threshold value. At a transmitting end (1) the system comprises means (4) for adjusting the transmission power, said means responding to the occurrence of the first control signal (Serr) by increasing the transmission power. In the system of the invention there is further provided at the receiving end a second means (9) for monitoring the rate of change of the received signal level and for producing a second control signal (Smp) if the rate of change exceeds a predetermined threshold value. The means (4) for adjusting the transmission power respond to the occurrence of the first (Serr) or the second (Smp) control signal by increasing the transmission power temporarily close to the maximum transmission power. |
