Patent Number Title Of Patent Date Issued
8244304 Method for synchronization of assemblies in a base station August 14, 2012
A method synchronizes assemblies in a base station to a reference clock signal. A local clock signal and a frame are formed in a first assembly. The clock signal and the frame are transmitted, using a synchronous transmission with a predictable propagation time, to a second assembly. A
8115677 Transmitter and receiver-side processing of signals transmitted or received with a smart antenna February 14, 2012
For transmitter-side processing of information it is decided in which direction of transmission signals for a receiver are to be transmitted, the direction of transmission being a linear combination of one of a number of antenna directional diagrams corresponding to a first plurality
8010160 System for combining output signals of two base stations August 30, 2011
A transmitter unit which is disposed between the first base station and the antenna arrangement contains a device for aggregate signal forming, a D/A converter and a transmission power amplifier. The first base station is connected on the output side to the device for aggregate signal
7548528 Method for assigning and method for scheduling codes for data transmissions, between a radio sta June 16, 2009
Codes are assigned and scheduled for data transmissions, between a radio station and at least one subscriber station, over a wireless interface of a radio communication system, in such a way that both for transmissions in the upward direction (uplink), from subscriber stations to the rad
7249008 Arrangement for runtime compensation of a runtime difference arising through emulation of a high July 24, 2007
An arrangement for runtime compensation of a runtime difference, arising through emulation of a high frequency signal, is disclosed, with a signal x(t), for emulation by a signal processing device, which emulates the signal x(t) with a signal x(t) and a device for determining a differenc
7170346 Arrangement for reducing non-linear distortions in an output signal of an amplifier stage January 30, 2007
A system reduces non-linear distortions in an output signal of an amplifier stage that is configured according to the feed forward principle. An amplifier stage input signal arrives at a main branch of an amplifier. The output signal of the amplifier, which is distorted in a non-line
7020473 Method for finding the position of a subscriber in a radio communications system March 28, 2006
A method for finding the position of a subscriber in a radio communications system combines transmission signals from subscribers to form a transmission sum signal, which is passed by cables from a base station to at least two antenna devices for transmission. Received signals from s
7016443 Synchronization method and system for clock signal sources, in particular in packet transmission March 21, 2006
The invention relates to a method for synchronization of clock sources in a communications system, in particular a radio communications system, having a large number of devices (PSTN, MSC, RNM, BSi, MSi, OMC) which communicate directly or indirectly with one another and have reference
6888485 Digital-analog converter May 3, 2005
A digital-analog converter for mobile radiotelephone base stations includes a D flip-flop and a modulator. The D flip-flop is clocked by a clock signal and a digital input signal is fed to an input of the D flip-flop to produce an output signal. The modulator multiplies the output signal
6825729 Frequency synthesizer with sigma-delta modulation November 30, 2004
A frequency synthesizer, especially for mobile radio base stations, transforms a digital input signal having a first frequency rapidly into a digital output signal having a second frequency. Similar to an N-fractional synthesizer, in the frequency synthesizer, the digital input signa
6285063 Resonant circuit having a resonant body mechanically oscillated by electrostatic or magnetic for September 4, 2001
The resonant circuit has at least one resonant body of a semiconductor material anchored on the surface of a semiconductor substrate, at least one first electrode being arranged at said semiconductor material, and at least one second electrode. The first and second electrode are arranged
