Investigates a new direct sequence spread spectrum method--complementary codes keying (CCK). The paper defines the complementary codes, analyzes its properties, synthesis and applications in local area wireless communications. Practical implementation algorithms of CCK are discussed and simulated in Matlab. Based on the simulation results, the performance of CCK is discussed. CCK can implement a high data rate with some processing coding gain.
