Optimized Companding Technique using Firefly Algorithm for PAPR Reduction in OFDM System
Abstract: AbstractThe current trends in wireless industry are based on multi-carrier transmission technique such as Orthogonal Frequency Division Multiplexing (OFDM) which provides high data rates and is highly immune to frequency selective fading. However, OFDM is handicapped with a major problem of high peak-to-average power ratio (PAPR), which gives rise to non-linear distortion, inter-symbol interference and out-of-band radiation. Several PAPR reduction techniques have been devised over the last few decades in …

Recognition of Unconstrained Handwritten Digits Using Feedforward MLP and Projection Profile
Abstract: AbstractThis paper presents a new approach to off-line handwritten numeral recognition using feedforward MLP and projection profile. Different writers have variations in their handwriting since each writer possesses own writing speed, own styles, sizes or positions for numeral or text. Recognition of handwritten numerals poses serious problems because of high variability in numeral shapes written by individuals. The performance of character recognition system depends heavily on what kind of features …

Widespread Dissemination of Library Resources through Remote Access
Abstract: AbstractPresently Libraries are providing a wide range of online resources to their users. They have named the means called “digital library” or “virtual library”. Consequently virtual library can be called as Internet based information retrieval system. The notion of “virtual library” is that any person who has a computer can access not only the resources of the library but also access diversity of information accessible on Internet, or on Intranet …

Investigations on PAPR Reduction using PTS Technique for OFDM Communication Systems
Abstract: AbstractOrthogonal Frequency Division Multiplexing (OFDM) is a spectral efficient technique for high data rate communication systems. It also provides robustness to multipath frequency selective fading but suffers from high peak-to-average power ratio (PAPR) and causes high power amplifiers to operate in the nonlinear region. In this paper partial transmit sequence (PTS) as PAPR reduction technique has been investigated. Mathematical modelling and Matlab simulation have been carried out to analyse its …

Hypothesis Analysis in Library and Information Science
Abstract: AbstractHypotheses can be regarded as suggestions of possible connections between actual facts or imagined ones. The question of the truth of hypotheses need not, therefore, always be raised. The necessary feature of a hypothesis, from this point of view, is that it should be stable in a determinate form, so that implications can be discovered by logical means.Keywords: Hypothesis and scientific method, need and purpose, collection of dataCite this ArticleRajaram …

Library Resource Sharing and Networking
Abstract: AbstractLibraries in the past had only written or printed documents. Written documents are manuscripts. These documents are always kept away and are not shared with other libraries. The users are expected to visit the library for consultation. The other category; the books were also not loaned to everyone and they were seldom shared with other libraries. With the introduction of printing by movable types, books started appearing in good number …

Simulation of Differential Space Time Block Coding
Abstract: AbstractIn such a coherent system, the underlying assumption is that the channel does not change during one frame of data. Thus, it can also be interpreted as the frame length is chosen such that the path gain change during one frame is negligible. This is basically the quasi-static fading assumption that we have used so far. There is a bandwidth penalty due to the number of transmitted pilot symbols. Of …
