The transient problem may be sufficiently addressed, and for this purpose, a further delay on the side of the decoding may be reduced if a new SBR frame class is used wherein the frame boundaries are not shifted, i. The transmission antenna andor the reception antenna isare fashioned as radio-frequency conductors and are arranged such that signals fed into the transmission antenna during at least one segment of the relative movement are received by the reception antenna by capacitive or inductive coupling. When the most recently used effective address matches the requested effective address, the cache manager identifies a corresponding cache location and retrieves the data from the identified cache location.
