Abstract :
Complementary codes are used in IEEE802.11b/g WLAN standard. For contention free operation with two or more users, the current CCK modulation can be enhanced by orthogonal Ear ZCZ sequence E(L,M,ZCZ) to provide contention free connectivity. In this paper, we simulate multi-user WLAN based on ZCZ modified CCK modulation for 11 Mbps data rate. Performance is analyzed to see the effect of zero correlation zone length (ZCZ) in Ear ZCZ sequence under two condition - (A) Length of Ear ZCZ sequence is fixed (B) Number of users are fixed. Simulation results are presented and discussed.
