| 20090279607 | Method and apparatus for video coding - In uniform superposition of two predictions toward a weighted superposition, such as in coding B frames, weighting is based on reliability of a reference picture used for determination of the prediction. Since there is a relationship between the reliability and the respective quantization parameter, coupling to the quantization parameter that is also known in the receiver also can be effected advantageously. | 11-12-2009 |
| 20090118847 | Method for Operating a Calculating Unit and Signal for Processing in a Calculating Unit - The invention relates to a method for operating a calculating unit, whereon at least one part of the signals and a marking relating to the quality of the signals and an attribute relating to a current transmission frequency of the marking are attributed. The inventive signal also comprises a marking relating to the quality of the signals thereof, and an attribute relating to a current transmission frequency of the marking. | 05-07-2009 |
| 20080261541 | Method and Device for Amplifying an Amplitude and Phase Modulated Electric Signal - The aim of the invention is to suppress interference caused by a mismatch of the power amplifier of a polar-loop transmitter. To achieve this, the crest factor of the output signal from the power amplifier is measured during operation to detect the state of the mismatch and to identify the modification of the transfer characteristic curve of the power amplifier. The crest factor that have been determined are compared with a target value and if the crest factor deviates from the target value, the bandwidth or the amplification of the amplitude closed loop is adapted accordingly., The transmitter can thus regulate the non-linear distortion that occur as a result of the mismatch. Said measures improve the linear behavior or degree of efficiency of the power amplifier. | 10-23-2008 |
