METHOD FOR CONTROLLING ADAPTATION AUTO GAIN

摘要

PURPOSE: A method for controlling an adaptation auto gain is provided to change parameter Pth of a second auto electric power control unit according to Eb/No of a received signal. CONSTITUTION: A method for controlling an adaptation auto gain includes two steps. A first step is to vary the intensity of a critical receiving signal according to quality of a receiving signal demodulated. A second step is to control an electric power gain for a base band signal being inputted from the intensity of the varied critical receiving signal and the intensity of a receiving signal of a base band which is changed with a digital. In the step to vary the intensity of the critical receiving signal, the intensity of the critical receiving signal is varied in the direction getting out of a range of the quantization in a digital change.
