Servus, Ich lese gerade Dokumente über das sogenannte Common Data Link: http://www.globalsecurity.org/intell/systems/cdl.htm und http://www.idlsoc.com/Documents/Symposiums/IDLS2007/IDLS2007_CDL.pdf Auf Seite 9 der PDF Datei erkennt man gleich, der PN Generator ist mit Multiplex und Spread verbunden. Die Frage ist, warum mit Multiplex? Zitat aus dem anderen Dokument: Multiplexer simultaneously provides multiple dedicated channels to users and mixes the data bits from each channel to form one aggregate bit stream. The method used to mix data from the channels is to organize the bits into multiplexer frames. These frames are then used to create the aggregate bit stream. A Multiplexer frame is a fixed length sequence of bits, with each user channel being allocated specific bit position within a frame. Synchronization (SYNC) code is a sequence of bits that is also included in each multiplexer frame. These SYNC codes provide the ability to identify each frame within the aggregate bit stream and the relative bit position within the frame. The Multiplexer provides a clock to each channel and accepts data bit according to the clock. The Multiplexer function is used in the Forward Link (FL) and in all modes of the Return Link (RL). Also das ist PN Code unabhängig. Mache ich hier einen falschen Gedanke? Gruss Owen
