Abstract: Wireless technology is expected to be the dominant mode of access technology in the future, a new data range of services such as multimedia and high speed data are being offered for delivery over wireless network. The IEEE 802.11 is known as Wireless LAN, to obtain higher data rates it is used with OFDM, which is defined a speed upto 54 Mbps in 5-GHz band. In this paper we present a technique to model the interleaver used in IEEE 802.11a and IEEE 802.11g based WLAN in verilog HDL using Quartus 9.0 web edition. Our technique is comprises of OFDM which provide higher operating frequency in addition to reducing the effects like intersymbol and interchannel interferences

Abstract: The placement of Flexible AC Transmission System (FACTS) devices in power system is of great significance to ensure the promising performance of the transmission network. The FACTS devices play an important role for power system security enhancement. The FACTS devices are used to regulate the active and reactive powers and to improve voltage profile, due to their robust, fast and flexible control characteristics. Due to their high capital cost, it is necessary to place these controllers optimally in a power system. Optimal placement of FACTS devices can control the line flows and can maintain the voltages at the desired level and so can improve the voltage stability. This paper presents Artificial Bee Colony (ABC) algorithm for finding the optimal location of Static Var Compensator (SVC) to reduce the real power losses and to improve the voltage profile of a power system during single line outage contingencies. ABC algorithm is an optimization technique based on the intelligent behavio
