Acquisition unit e.g. for digital TDMA modem, has circuit arrangement for determination of optimum sampling time of digital data stream, generated by over-sampling with given number of samples per symbol from baseband signal

摘要

The acquisition unit has a circuit arrangement for the determination of an optimum sampling time (1) of a digital data stream, generated by over-sampling with a given number of samples per symbol from a baseband signal. A circuit determines the beginning of a transmission frame (2) and a circuit determines the carrier frequency (3) of a digital data stream. A combined circuit (4) has a common data input, having the circuit determining the beginning of a transmission frame and the circuit for determination of the optimum sampling time.
