Patent number: 6336032Abstract: The phase of a transmitted signal is regulated in a device which is part of a system for electromagnetic signal transmission. The transmitted signal has periods when it contains information and periods when it does not contain information. The modulation position of a phase shifter which has a linear and a non-linear range is controlled. Power of the signal is amplified. Unwanted phase shifts in the signal transmitted by the device caused within the power amplifier are detected, and the information content of the signal is detected. The phase shifter is reset to a particular predetermined modulation position in the event of detection of the absence of information in the signal. The predetermined modulation position to which the phase shifter is reset is preferably situated within the linear range of the phase shifter.Type: GrantFiled: December 22, 1998Date of Patent: January 1, 2002Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Johan Bergman, Per Löfving, Jan Robert Hedström, Thorsten Kraus

Patent number: 6148217Abstract: The present invention discloses a method for quickly and easily adjusting the gain of an antenna system. According to an exemplary embodiment of the present invention, the output power of the base station's antenna system is adjusted during the base station's installation process. In the adjustment procedure, the output power of the base station is set to a predetermined value. When a switch is closed, the output power of the base station's associated active antenna system is measured and compared to a stored reference value. If the comparison indicates that the measured output power is above or below the stored reference value, the attenuation of the antenna system is automatically changed in order to properly adjust the gain of the antenna system. The present invention facilitates base station installation by providing a fast and easy gain adjustment method which requires no intervention from the base station or telephone network.Type: GrantFiled: August 19, 1998Date of Patent: November 14, 2000Assignee: Telefonaktiebolaget LM EricssonInventors: Ulf Skarby, Kristian Lindskog, Per Lofving
