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,Z_CZ) 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 (Z_CZ) 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.
