Short Communication on Fingerprint Image Enhancement and its Future Scope
Abstract: The fingerprint images are rarely of perfect quality, due to the reasons like variations in impression condition, skin condition, scanning devices or may be due to non-co-operative attitude of the subject. This degraded quality of image can result in a significant number of spurious minutiae being created and genuine minutiae being ignored. A vital step in studying the statistics of fingerprint minutiae is to reliably extract the minutiae feature from …

Comparison of Three Interpolation in OFDM Systems
Abstract: Doppler shift and channel induced fading effects are more likely to induce inter carrier interferences (ICI), which are the challenging research area in the orthogonal frequency division multiplexing (OFDM). This paper uses channel estimation for canceling the effects of ICI from the received signals. One dimensional frequency domain comb-type channel estimation are considered because of its low computational complexity and effective tracking ability of the fast fading channel. The channel …

An Improvement of Out-of-Band Suppression in Common-Gate LNA with Transformer-Based Input Matching Network for BLE Applications
Abstract: The purpose of this paper is to improve out-of-band suppression in capacitive cross-coupling common-mode LNA with transformer-based input matching for BLE applications. Starting from an overview of the transformer-based matching network, the problematic issue is addressed through analytical considerations and its solution is presented. Transformer-based matching introduces an undesired peak response by an extra conjugate pole pair owing to the imperfect magnetic coupling of the transformer which degrades the suppression …
