DETECTION METHOD FOR PHASE-MODULATED SYMBOLS WITH A CORRELATOR-BANK

摘要

PROBLEM TO BE SOLVED: To provide a detection method for phase-modulated symbols with a correlator-bank. SOLUTION: The invention relates to a method for the detection of a symbol from a received signal wherein the symbol is a selected symbol out of a predetermined set of symbols, wherein each symbol of the predetermined set is a CCK symbol comprising a sequence of chips wherein each of the chips is PSK- modulated according to a selected modulation code, wherein each of the selected modulation codes comprises a first sub-modulation code which is a selection from a plurality of first sets of predetermined phase modulating elements and a second sub-modulation code which is a selection from one second set of predetermined phase modulating elements wherein at least one of said predetermined phase modulating elements of said second set is a complex value such as defined in the high-speed IEEE 802.11b standard, wherein a modulation code is selected from said modulation codes which correlates according to a correlation method with the received signal.
