Abstract:
1. Method for calibrating a digital communication station, which uses an initial ranging procedure for measuring channel parameters in a communication channel, comprising: transmitting a signal to the communication station, which transfers the communication station into an initial ranging mode; measuring parameters of the signal transmitted by the communication station during the initial ranging cycle; calculating necessary calibration adjustments to the communication station; and adjusting the communication station; wherein after transmitting a signal to the communication station, which transfers the communication station into the initial ranging mode, no response to the signal transmitted by the communication station is issued causing the communication station to perform an entire initial ranging cycle, gradually increasing the transmitting power of the signal, despite the signal transmitted by the communication station having being received for measuring parameters, and wherein the initial ranging procedure is repeated to check the success of the adjustment and after a predetermined number of initial ranging procedures leading to remaining adjustments to the communication station the communication station is discarded.
