Abstract:
A method for automatically controlling transmission power of a near-end and far-end transceiver pair in communication with each other, comprising the steps of:determining if the near-end and far-end received signals from the far-end and near-end transceivers, respectively, have signal strengths that are simultaneously attenuated by a prescribed amount below their respective values occurring during clear weather fee-space conditions; and if so, then increasing the transmission power of the near-end and far-end transceivers as necessary to restore, but not exceed, the strengths of the near-end and far-end received signals to their respective values occurring during clear weather free-space conditions, wherein during intervals while the signal strengths of both the near-end and far-end signals are not simultaneously attenuated by a prescribed amount below their respective values occurring during clear weather free-space conditions, the following steps are performed: determining if the bit error ratio of only one of the near-end and far-end received signals from the far-end and near-end transceivers, respectively, is degraded such that there are errors in excess of an acceptable threshold for a given service during clear weather free-space conditions; and if so, then triggering a limited increase in the transmission power of a corresponding far-end or near-end transceiver, respectively to reduce measured bit errors in said one degraded received signal until (1) the said degraded received bit error ratio is restored to acceptable levels, or (2) a predetermined upper limit of allowable clear-weather transmitter power increase is reached.
