1. Technically, the 802.11b standard uses Complementary code keying ( CCK ) as its modulation technique.
2. In reaching 5.5 Mbit / s and the full rate of 11 Mbit / s, QPSK is employed, but has to be coupled with complementary code keying.
3. Polyphase complementary codes, first proposed by Sivaswamy, 1978, are codes where each element is a complex number of unit magnitude and arbitrary phase, or more specifically for 802.11b is one of [ 1,-1, j,-j ].
4. The complementary codes first discussed by Golay were pairs of binary complementary codes and he noted that when the elements of a code of length N were either [-1 or 1 ] it followed immediately from their definition that the sum of their respective autocorrelation sequences was zero at all points except for the zero shift where it is equal to K * N . ( K being the number of code words in the set ).
