Abstract
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 complementary coded keying (CCK) symbol having a sequence of chips wherein each of the chips is phase shift keying (PSK)-modulated according to a selected modulation code wherein each of the selected modulation codes has 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 the predetermined phase modulating elements of the second set is a complex value such as defined in the high speed IEEE 802.11b standard, wherein a modulation code is selected from the modulation codes which correlates according to a correlation method with the received signal.
