摘要： An oscillator is disclosed that is tunable to discrete values, and includes a tuning element which can be connected via a switching device. A rectifier circuit is connected to the output of the oscillator and forms a clock signal from the oscillator signal. The oscillator circuit contains a phase delay circuit having a switching input, a clock signal input which is coupled to the output of the rectifier circuit, and a switching output coupled to the switching device. The phase delay circuit has a comparison circuit for comparison of a phase of the clock signal that is applied to the signal input with a reference phase. This phase delay circuit is designed to emit a switching signal after application of an activation signal to the switching input and after the phase of the clock signal which is applied to the signal input matches the reference phase. In consequence, the switching process is delayed until the step-function response of the output signal of the oscillator does not cause a sudden phase change in the clock signal.

摘要： A method is disclosed, including identifying a preamble in a frame, where the preamble has a preamble length 1. M data items received in succession are stored. The m data items once divided into n portions, where the data items in each portion have respectively been received at successive times and where m and n are natural numbers and the following applies to m and n: m>n, m>1, n>1. The n portions are respectively correlated to the expected values to form component correlation results. Delaying the component correlation results, with at least two component correlation results being delayed by different lengths. The method also includes combining the delayed component correlation results to form a total correlation value. The total correlation value is used to determine whether the m received data items contain the preamble of a frame.

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： In a frequency generating system, a triple/single local-oscillator concept for receiving and transmitting in the lower frequency band, transmitting in the upper frequency band, and receiving in the upper frequency band is used for a dual-band transceiver so that a single band-switched VCO can be used as local oscillator for setting the frequency in all four possible operating cases. The system can be used, for example, in highly integrated dual-band mobile parts for GSM 900/1800 mobile radio.

摘要： Offset voltage compensation in baseband in a radio receiver path is achieved by control and programming signals which are required in any case to set the desired states in the circuit module. For this purpose a sequencer is started which is integrated on the module and provides additional control signals that are defined in time, without any additional computation power being required from a separate baseband processor. The offset voltage compensation can be used in receiver and transceiver chips for portable mobile radios, for example for GSM or PCN/PCS.
