Anomaly Detection is the term which is widely used in Data Mining. Anomaly Detection means Fraud Detection. Anomalous Intrusion became a key issue in security because of the heavy data in network. So it becomes hard to prevent such attacks. Previous techniques works only on batch mode means those techniques are not applied for large dataset. For this purpose it is important to find technique which...
As the need of internet is increasing day by day, the significance of security is also increasing. The enormous usage of internet has greatly affected the security of the system. Hackers do monitor the system minutely or keenly, therefore the security of the network is under observation. A conventional intrusion detection technology indicates more limitation like low detection rate, high false alarm...
This paper presents a joint channel estimation and data detection (JCEDD) for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) system. Initial estimate of the channel is obtained using semi-blind channel estimation (SBCE). The whitening rotation (WR) based orthogonal pilot maximum likelihood (OPML) method is used to obtain the channel estimate. The estimate is...
