PROBLEM TO BE SOLVED: To provide a method for processing spread spectrum signals. SOLUTION: A continuous signal of a comparatively high frequency is received (1610). This signal is sampled at a basic sampling rate whereby a resulting sequence of time-discrete signal samples is provided, which are in turn quantized into a corresponding level-discrete sample value (1620). A plurality of data words are formed, which each includes one or more consecutive sample values (1630). Information obtained from these data words is correlated with at least one representation of a signal source specific code sequence (1640), which has been pre-generated in the form of a code vector (1600). The correlation step specifically involves correlating at least each vector in a sub-group of the code vectors with at least one vector that has been derived from the data word. Thereby resulting data are produced (1650). COPYRIGHT: (C)2010,JPO&INPIT |
