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 |

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 |

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 |
