METHOD AND DEVICE FOR PHASE REGULATION

摘要

The invention relates to a method for the regulation of transmitted phase of a signal in a device (100) which is part of a system for electromagnetic signal transmission, in which system the transmitted signal has periods when it contains information and periods when it does not contain information. The method comprises the control of the modulation position of a phase shifter (110) which has a linear and a non-linear range, power amplification (120) of the signal, detection of unwanted phase shifts in the signal transmitted by the device (100) caused within the power amplifier (120), and the detection of the information content of the signal, and is characterized in that the phase shifter (110) is reset to a particular predetermined modulation position phi ini in the event of detection of the absence of information in the signal. The predetermined modulation position phi ini to which the phase shifter (110) is reset is preferably situated within the linear range of the phase shifter.
