The method of adjustment of gain and phase of a signal for input to an amplifier to adjust the relative phase and gain on between signals that combine

摘要

b adjustment method of phase and gain ratio between signals that combine d a system control of gain and phase performs an adjustment of gain (or phase).Based on the results of a previous setting of the gain (or phase), after an intermediate adjustment phase (or gain).A gain adjustment based on the results of a previous gain adjustment, rather than the results of a intermediate adjustment phase.An adjustment phase, based on the results of an adjustment of the previous stage, instead of on the results of an intermediate adjustment of gain.Thus, the increase in the error signal mentioned above does not occur because an adjustment of gain is based on the results of the previous gain adjustment.And an adjustment phase, based on the results of the previous stage settings.According to another aspect of the present invention.The control system of gain and phase adjustment of a gain (or phase) in parallel with the detection results of an adjustment phase (or gain).In this way taking advantage of the delay between the fitting and the detection of the error signal therefrom, to improve the rate of convergence.For example, the system of control of gain and phase adjustments can be only rotated of gain and phase, and make an adjustment of the gain (or phase).While detects the error signal resulting from an adjustment of the phase (or gain) precedent.When the error signal resulting from the adjustment of the gain (or phase) is detected, the control system of gain and phase adjustment makes a phase (or gain)Using the results detected adjustment phase (or gain) precedent.
