This paper proposes a downlink resource scheduling technique for maximized throughput with reduced Block Error Ratio and improved fairness among different users across the cellular region. Resources are allocated to users on the basis of Channel Quality Indicator feedback values in a way that the data rates are increased without compromising on Block Error(More)
Download Accelerator Plus (DAP) is one of the most popular download managers [1] due to its free availability, download speed and versatility. This software records download activities across multiple files which include history, registry, RAM, swap and temporary files. This paper analyzes a) the log files (with .DAT extension), b) windows registry entries,(More)
Orthogonal Frequency Division Multiplexing (OFDM) is a widespread adopted technique for wireless and wired communication systems because of its inherent feature of the spectral efficiency and robustness to channel impairments. The throughput deterioration of the OFDM system due to pilots can be reduced by minimizing the density of pilots. A Modified Minimum(More)
This paper scrutinizes the structure of jump-controlled LFSRs for resistance against generalized correlation attack based upon Constrained Levenshtein Distance(CLD) measure. It proves that for a given number of cipher text bits, CLD computation is independent of Jump index. However, based upon the inherent relation between the jump index and deletion rate,(More)
Free Download Manager (FDM) is one of the most popular download managers due to its free availability, high download speed and versatility. It contains a lot of information that is of potential evidentiary value even if a user deletes web browser history, cookies and temporary internet files. This software records download activities across multiple files(More)
Radio Frequency Identification (RFID) tags possess the ability to uniquely identify every individual item at low cost. This emerging RF technology is well suited for supply chain management and is expected to replace barcodes in the near future. However, unlike barcodes, these tags have an extended range in which they are allowed to be queried by a reader.(More)
Orthogonal Frequency Division Multiplexing (OFDM) is attractive for high data rate transmission due to spectral efficiency but is known to be sensitive to synchronization errors(symbol time and frequency offset)[1]. Mobility is the basic feature of most of present day techniques that employs OFDM at the backend but Doppler frequencies generated due to the(More)
