The concept of Orthogonal Frequency Division Multiplexing (OFDM) was initiated and well prominent since 1966 and gradually reached to its development into standard system form during 1990. Large amounts of digital data, with high data rate, reliable communication over fading channels can be transmit over radio waves that is why OFDM is known to be an attractive technique for multicarrier transm...

Feature Reduction is the reduction of features. Most of the intrusion detection approaches focused on feature selection issues such as irrelevancy, redundancy and length of detection process. These issues will degrade the performance of system. The performance of the system is improved by three feature selection methods involving correlation based feature selection, Gain Ratio and Information G...
