With the rapid growth of digital communication in last few years, the need for high speed data transmission is increased. To support the high speed services like video, data and voice need efficient wireless systems. OFDM is a most efficient multicarrier modulation system used for achieving high data rates in mobile environment because of its multicarrier modulation technique and ability to convert a frequency selective fading channel into several nearly flat fading channels. Also, it becomes very efficient technique for data transmission over multipath fading environment due to its...

The past few decades have witnessed a renewed interest in developing natural products from plants into insecticides and bioregulators. Their role in development of resistance in plants to insects has made them attractive candidates for manipulation in pest control programmes. Acacia auriculiformis A. Cunn., a medicinal plant rich in polyphenols, was evaluated for its pesticidal properties against the melon fruit fly, Bactrocera cucurbitae (Coquillett), a major pest of cucurbitaceous crops. The crude extracts, partitioned fractions and purified fractions obtained from bark of A. auriculiformis...
