    摘要: A device for reading information stored on an information plate (1), and/or for writing information on an information plate (1), includes a loading mechanism for loading and unloading the information plate (1). The loading mechanism includes at least one movable scanning lever (5) for detecting the position of the information plate (1). The lever is designed for making contact with the plate edge of the information plate (1). A position sensor is provided for supplying position information on the position of the information plate (1) in dependence on the position of the scanning lever (5).

    摘要: Carrier frequency and frames are synchronized in bursty data transmissions over unknown channels that cause inter-symbol interference. The synchronization procedure comprises two stages. The first stage performs a time-domain processing of samples to exploit a periodic signal repetition and to extract the coarse timing, the frequency offset and also to resolve frequency ambiguities. The second stage estimates the fine time offset of a received modulation signal. A coarse estimate of a frame start position of a received sequence of desired data samples may be improved by using the coarse timing estimate to generate frequency-domain received samples. A frequency-domain correlation is then determined between the frequency-domain received samples and noiseless samples. When using a fixed number of training samples, a “sandwich” preamble (“sandamble”) is utilized to achieve greater efficiency than a conventional repetition preamble.
