摘要： In a method for estimating a frequency offset (fe, Ωe) of a modulated bandpass signal (s) with an assumed carrier frequency (Ω0) in a mobile radio receiver, times (τj) of the zero cross-overs of the bandpass signal are determined in a first step. Using the times (τj) of the zero cross-overs and the assumed carrier frequency (Ω0), the required frequency offset (fe, Ωe) is estimated in a further step by calculating the DC component of an instantaneous frequency which is given by the frequency of the bandpass signal less the assumed carrier frequency.

摘要： A detector for zero crossings and a counter which is connected to it are used to determine the time intervals between the zero crossings of the received signal or of an intermediate-frequency signal which is produced from the received signal, and for detection of the digital signal data. In this case, a sequence of determined zero crossing intervals can be stored in digital form in a shift register chain, and can be compared in a classification device with previously stored interval sequences. Furthermore, a frequency offset can be determined by averaging the zero crossing intervals and can be compensated for by suitable selection or modification of the previously stored interval sequences, in which case the latter can also be used during the synchronization phase. The synchronization process may, furthermore, be assisted by payload data identification.

摘要： When data bursts are transmitted between a base station and a mobile receiver, a changeover is made between a plurality of modulation methods during an existing radio link for modulation of the data. For resynchronization of the receiver in the event of the changeover, synchronization information items are determined from a first part (ET) of the data burst modulated by a first modulation method, and are used for synchronization with a second part (ZT) of the data burst modulated by the second modulation method.

摘要： A receiver circuit for a mobile radio receiver has a controllable amplifier with a variable gain level, an analog-digital converter stage, a digital filter configuration for the purpose of channel selection and a signal strength estimator. The signal strength estimator is connected downstream of the filter configuration in the signal path and has the purpose of determining the signal strength in the selected user signal. The amplifier is controlled in dependence on the user-channel signal strength determined by the signal strength estimator.

摘要： A receiving device for angle-modulated signals performs the channel selection in a digital manner rather than an analog manner. A receive signal is preferably initially converted to an intermediate frequency band, filtered and A/D converted. The receive signal is subsequently converted to the baseband and channels are selected in a digital manner through the use of a digital complex multiplier before the receive signal component of the selected transmission channel is demodulated and the corresponding symbols are detected through the use of a differential demodulator.

摘要： The method is based on a signal interval (DB) which comprises a first part (ET) (which is modulated using a first modulation method (GFSK)) of the signal interval and a second part (which is modulated using a second modulation method (DMPSK)) of the signal interval. The channel parameters (c(i)) relating to the second part (which is modulated using the second modulation method) of the signal interval are determined using a received data signal (a(i); p(i)) from the first part (ET) of the signal interval (DB).

摘要： In a method for estimating a frequency deviation between a received spread-spectrum code signal and a local frequency signal, the received spread-spectrum code signal is despread using a local spread-spectrum code. The despread signal is integrated over a particular integration period. From at least two successively obtained integration values, a phase change value characteristic of the phase change between the two integration values is calculated. From this, the frequency deviation is determined.

摘要： A method for calculating zero-crossing reference sequences ({ti}) for the data detection of a sequence of zero crossings ({{circumflex over (t)}i}) of a received signal is disclosed. The data detection is determined in a receiver, wherein the received signal is based on a data symbol sequence ({dk}) angle-modulated at a transmitter and transmitted to the receiver. The zero-crossing reference sequences ({ti}) are calculated in accordance with an equation specifying an output of a finite state machine that describes, at least approximately, the signal generation in the transmitter.
