Verfahren und Vorrichtung zur Ermittlung für ein Spreizspektrumübertragungssystem

摘要

The invention relates to a probing apparatus for a spread-spectrum communications system, such as a Code Division Multiple Access (CDMA) communications system. The apparatus comprises an antenna array (528) including at least two antenna elements arranged to transmit a first signal, and a second signal. The first signal selectively comprises at least probing information and the second signal comprises at least data. The probing information of the first signal is substantially simultaneous and orthogonal to the second signal.
