Abstract: A system for generating a traveling field free line, traveling along a propagation direction different from the orientation of said traveling field free line, said system comprising at least a first and a second coil assembly, wherein said first coil assembly is configured for generating a first stationary field free line at a first location when a current is flowing in the first coil assembly and the second coil assembly is current free, and wherein said second coil assembly is configured for generating a second stationary field free line at a second location, when a current is flowing in the second coil assembly and the first coil assembly is current free. The system further comprises a controller configured for driving the first and second coil assemblies with corresponding driving currents synchronized with each other, such that said traveling field free line travels along the propagation direction from a first location towards a second location.

Abstract: For synchronizing a data block in a receiver, there are transmitted consecutively and prior to the data block: a first bit sequence of alternating "0" and "1" levels for determining the bit clock and a second bit sequence for determining the block synchronization by correlation. In known methods of determining the bit clock, the phase range of the individual bits of the received digital signal is divided into sub-intervals and the phase position of the bit clock is determined on account of the number of edges in these sub-intervals. In order to avoid fading and phase jitter having a detrimental effect on the bit synchronism, more specifically when transmitting through radio transmission links, N-phase-shifted clocks having the same clock frequency are generated in the receiver by means of which the first bit sequence is sampled.
