摘要： In a method to compensate for a step DC disturbance (1) in a baseband signal in a homodyne radio receiver, the time profile of the step DC disturbance within a burst is determined. In order to produce a step-corrected baseband signal, the determined time profile (2) is then calculated from the digitized baseband signal.

摘要： A channel filter (200) with a variable pass bandwidth has a first low-pass filter (200.2) on the input side and is driven by a means (30) for controlling the pass bandwidth as a function of the adjacent channel interference. A first input of the control means (30) is connected to the first low-pass filter (200.2), and a second input is connected to a bandpass filter (200.4) which is connected in parallel with the channel filter (200). The signal path which contains the low-pass filter (200.2) contains a means (37) for removing a DC signal component or DC component.

摘要： A mobile station is disclosed for processing differing radio standards such as GSM/GPRS/EDGE and TD-SCDMA. The mobile station includes a channel decoding unit and a coding unit. The signals of both radio standards are processed both with the coding unit and with the channel decoding unit. The coding unit and the channel decoding unit are arranged in the baseband chip of the mobile station. The TD-SCDMA-specific algorithms can be generated by means of a coprocessor that is electrically connected to the baseband chip or integrated in the baseband chip.

摘要： An entirely integrated EMI filter is based on a flexible multi-layer strip material. An EE or EI core comprises two side pillars and one middle pillar and forms a closed magnetic circuit. The middle pillar has an air gap. A first winding and a second winding respectively are wound around the two side pillars in a same winding direction. The middle pillar is wound with a third winding and a fourth winding, or with only a fifth winding. Passive components (e.g., all passive components) of the EMI filter are integrated into one core so that in its differential mode, insertion loss is significantly reduced, the size and volume are reduced, and the distribution constant of the EMI filter has less impact on the filter's performance.
