    摘要： An apparatus for finely synchronizing code signals with an encoded received signal includes a sampling device for sampling the received signal at regular sampling intervals, a pulse shaper for shaping the sampled received signal pulses in order to output a first and second pulse-shaped sample in dependence on an autocorrelation function, a buffer for buffering the two samples, a code signal generator for generating the code signal, correlation devices for correlating the generated code with the two buffered samples to form two correlation values, and an interpolation device for forming an interpolation value as a function of the two pulse-shaped samples and the deviation between the two correlation values.

    摘要： A device for holding an object, and an assembly for holding and rotating an object. The device includes a base, a series of posts, each of which is equidistant from a center point of reference and further pivotably holds a follower rotationally linked to all other followers. Each follower has a gripping portion dimensioned to hold an object. An actuator serves to displace the followers radially about the post holding it creating a motion that causes the gripping portions to move either towards or away from the center reference point, dependent upon the displacement of the actuator. As all followers are rotationally linked, each follower of the device rotates to a substantially equal degree.

    摘要： A method is described for estimating channel impulse responses of a mobile radio channel with a broad bandwidth by a code division multiplexing method, and with a synchronization channel continuously transmitting sequences to mobile radio receivers. The sequences are provided for synchronization of each mobile radio receiver and are known to each of the mobile radio receivers. The transmitted sequences have pilot symbols for identifying the synchronization channel, and the pilot symbols are transmitted at points that are known to the receivers within a time slot. When searching for and identifying the synchronization channel, the pilot symbols and, possibly, further symbols and sequences which are known in the receivers, are evaluated to estimate the delay times and the complex amplitudes, of the mobile radio channel responses.
