Detection of Drive-by Download Attacks Using Machine Learning Approach
Abstract
Drive-by download refers to attacks that automatically download malwares to user’s computer without his knowledge or consent. This type of attack is accomplished by exploiting web browsers and plugins vulnerabilities. The damage may include data leakage leading to financial loss. Traditional antivirus and intrusion detection systems are not efficient …
Window Based Pulse Shaping Technique for DVB-T System
Abstract
Digital Video Broadcasting (DVB) is an international standard for digital television services. Many versions of DVB are available for commercial use including DVB-H, DVB-S, DVB-C, DVB-T, and DVB-IPTV. In this paper, we focus on the performances of DVB-T system. In DVB-T system Orthogonal Frequency Division Multiplexing (OFDM) has been …
Fourier Transform Based Early Detection of Breast Cancer by Mammogram Image Processing
Abstract
Breast cancer is very common among the World’s women population. Early detection of breast cancer can save life. Mammography based diagnosis is considered as the most effective to detect breast cancer. But, mammogram images often lead to misdiagnosis due to their low contrast nature. Recent studies show that mammography …

Effects Of Filters on DVB-T Receiver Performance Under AWGN, RAYLEIGH and RICEAN Fading Channels
Abstract
Digital Video Broadcasting–Terrestrial(DVB-T)has become a very popular technology for terrestrial digital television services.DVB-T is based on Orthogonal Frequency Division Multiplexing (OFDM)technique. OFDM is considered suitable for the DVB-T system because of its low inter-symbol Interference(ISI).DVB-T has some limitations too including large dynamic signal range and sensitivity to frequency error. …
Effects of Filters On The Performance of DVB-T Receiver
Abstract
Digital Video Broadcasting-Terrestrial (DVB-T) is an international standard for digital television services. Orthogonal Frequency Division Multiplexing (OFDM) is the core of this technology. OFDM based systems like DVB-T can handle multipath fading and hence it can minimize Inter Symbol Interference (ISI). DVB-T has some limitations too namely large dynamic …
