As the high speed expanding scheme adopted by IEEE802.11b standard, the Complementary Code Keying modulation technology can only perform well in error probability with high signal noise ratio. However, when SNR is comparably low or the number of users in the same channel augments suddenly, the system’s error probability soars. On the basis of the research on Complementary Code Keying, RS coding and decoding algorithms, this paper analyzed code parameters’ influence on error correction and accordingly promoted a coding scheme suitable for Complementary Code Keying: RS（255,239）. Simulation Results demonstrated that once SNR is upon 5.1dB the system performance would be greatly enhanced.
