An original complex IQ signal of a signal branch of N signal branches and a processed real signal of the signal branch are received. A processed complex IQ signal of the signal branch is calculated from the processed real signal and the original complex IQ signal of the signal branch. Then, a difference between the processed complex IQ signal and the original complex IQ signal is calculated. Finally, control values of a correction function of the signal branch are calculated on the basis of the calculated difference. The calculated control values are supplied to the correction function of the signal branch. The receiving, calculating and supplying operations are performed for all N signal branches.

Method and apparatus of forward link and reverse link power control in a cellular wireless communication system
ActiveUS7480516B1Incorrect adjustment of the forward link traffic channel gain may be avoidedAdjustment errorPower managementResonant long antennasTransceiverCommunications system
A cellular wireless communication system includes base transceiver stations and mobile stations that operate with a closed loop power control. The mobile tracking is performed based on the lock in and lock out thresholds by the base transceiver stations. A forward link power control bit is decoded from the reverse channel. An additional threshold is introduced for determining at the base transceiver station whether the decoded forward link power control bit is valid or invalid. The finger energies obtained from a finger processor formed by a RAKE receiver of the base transceiver station are compared to the additional validation threshold. The additional validation threshold is independent of the tracking thresholds and usually greater than them. The validation performance may not be affected by low signal / noise. The forward link traffic channel gain of the base transceiver station is controlled in response to the invalidity of the decoded forward power control bit. The decoding of the reverse link power control bit and the validity determination of the decoded reverse link power control bit are performed by similar methods to those of the forward link power control bit. With improved validation methods, the forward link and reverse link transmission power is more accurately controlled.
