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 avoiding transients during switching processes in integrated circuits, a module of the integrated circuit is switched from a first operating state to a second operating state, a load change occurring thereby. In this case, it is ensured that the occurring quotient of load change and time duration for the transition from the first operating state to the second operating state does not exceed a predetermined limit value, thereby reducing or avoiding transients associated with such switching.

摘要： In a method for estimating a sequence of input data symbols of a CPFSK-modulated data signal transmitted via a faulty channel, in the course of an ACS operation for calculating a transition metric value, an estimated value is determined for the replacement symbol occurring during the linear approximation of the CPFSK. That estimated value is considered in calculating the transition metric value.

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： The present invention is directed to a receiver for a wire-free communication system for reception of a received signal which is modulated using a digital modulation method having a first frequency conversion device for production of a frequency-converted received signal by conversion of the received signal to an intermediate frequency. The receiver further includes a pre-filter for production of a filtered received signal from the frequency-converted received signal such that the received signal is band-limited, and an analogue/digital converter for production of a binary received signal from the filtered received signal by comparison of the filtered received signal with a level threshold. In addition, the receiver includes a phase reconstruction device for production of a phase-reconstructed received signal by reproduction of the phase of the received signal from the time intervals between zero crossings of the binary received signal, and a mapping device for production of a bit sequence by mapping symbols from the phase-reconstructed received signal onto this bit sequence using the digital modulation method.

摘要： A radio receiver with a low intermediate frequency has a first mixer stage that can be fed with a modulated input signal and at whose output a complex intermediate frequency signal can be derived. Connected downstream of the first mixer stage is a limiting amplifier at whose output the intermediate frequency signal is present in a discrete-value and continuous-time fashion. A sampling device, for sampling the intermediate frequency signal, and a digital demodulator unit are connected to the output of this limiter. The demodulated input signal can be derived at the output of this digital demodulator unit. The present radio receiver requires a low chip area in conjunction with low power consumption, but offers a high sensitivity and accuracy based on the digitally implemented demodulation.
