| 20130034243 | Method and Arrangement For Noise Cancellation in a Speech Encoder - The present invention relates to a method and arrangement for an improved noise canceller in a speech encoder. Sound signals are captured at a primary microphone in conjunction with a reference microphone. An adaptive shadow filter is adapted to the correlation between the signals captured at the primary and reference microphones. Further, a diffuse-noise-field detector is introduced which detects the presence of diffuse noise. When the diffuse-noise-field detector detects diffuse noise, the filter coefficients of the adapted shadow filter is used by a primary filter to cancel the diffuse noise at the signal captured by the primary microphone. Since the filter coefficients of the adapted shadow filter only is used for cancellation when diffuse noise is solely detected, cancellation of the speech signal is avoided. | 02-07-2013 |

| 20090197606 | HIGH-SPEED SERVING CELL CHANGE - A device receives a measurement report generated by user equipment, and determines whether a serving cell for the user equipment should change from a source cell to a target cell based on the measurement report. The device also configures the source cell and the target cell for the serving cell change when it is determined that the serving cell for the user equipment should change, and transmits, via the target cell, a serving cell change message to the user equipment using a common network temporary identifier. The device further receives, from the user equipment, an acknowledgment of the serving cell change. | 08-06-2009 |
