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<sub>CZ</sub>) to provide contention free connectivity. In this paper, we simulate multi-user WLAN based on ZCZ modified CCK modulation for 11 Mbps data rate.(More)
The study was undertaken to investigate the mutagenic activity of hydrazine hydrate a structural isomer of the nucleic acid base thymidine in barley. The treatments were administered alone or in the presence of maleic hydrazide and X-rays. Hydrazine was able to produce chlorophyll mutations in the M1-generation itself if applied alone, in a mixture or as a(More)
