CCK

(Complimentary Code Keying) A direct sequence spread spectrum (DSSS) coding method used in the 802.11b wireless LAN standard for 5.5 and 11 Mbps. The slower 1 and 2 Mbps specifications use Barker coding which has a chip rate of 11 compared to 8 in CCK. CCK also provides up to 64 coding patterns, whereas Barker uses only one. Unlike CDMA, which overlaps transmissions using different codes, CCK uses the different codes to transmit more data serially (TDM). Contrast with OFDM. See CCK/OFDM and chip rate.
