AB  - IEEE 802.15.4 standard is widely used in the field of low-power, low-cost and low-bit rate communications. In this paper, we analyze performance of an IEEE 802.15.4 network operating in 2450 MHz ISM (Industry, Science and Medicine) band in the presence of κ–μ fading, interference and additive white Gaussian noise. A novel analytical expression for the chip error probability evaluation of an IEEE 802.15.4 wireless channel has been derived. Its correctness is validated by Monte Carlo simulations. Capitalizing on the derived CEP expression, the symbol error probability and the packet error probability are also evaluated for various values of the κ–μ fading channel parameters and signal-to-interference-to-noise ratios.

AB  - The paper describes in detail the skeletonbased algorithm for the automatic extraction of fingerprint minutiae. These distinguishing characteristics are used both in the manual and automatic (AFIS-Automatic Fingerprint Identification System) fingerprint matching process for identification purpose. Proposed enhancement algorithm, utilizing multiscale orientation field estimation along with Log-Gabor filters in frequency domain, significantly improves fingerprint image quality, resulting in reduced number of falsely minutiae extracted. Results of experiments conducted on collections of fingerprint images show competitive performance of proposed algorithm.

AB  - Reliable extraction of true minutiae in fingerprint image is critical to the performance of an automated fingerprint identification system (AFIS). In order to utilize AFIS in law enforcement agencies first step is to digitalize an archive of fingerprints obtained by ink method. For improving the quality of automatically extracted minutiae (both in number and type) enhancement is previously performed, but, nevertheless, quite a number of spurious minutiae (especially in blurry or regions containing scars and creases) are extracted. It is crucial for AFIS performance that number of extracted (and consequently saved in fingerprint template) spurious minutia is minimized to maximal extent. In order to do so, we propose directional Log-Gabor filtering in frequency domain. Results proved to be preferable for a wide range of input digitized fingerprint images

AB  - Extensive research of automatic fingerprint identification system (AFIS), although started in the early 1960s, has not yet give the answer to reliable fingerprint recognition problem. A critical step for AFIS accuracy is reliable extraction of features (mostly minutiae) from the input fingerprint image. However, the effectiveness of a feature extraction relies heavily on the quality of the input fingerprint images. This leads to the incorporation of a fingerprint enhancement module in fingerprint recognition system to make the system robust with respect to the quality of input fingerprint images. In this paper we propose an adaptive filtering in frequency domain in order to enhance fingerprint image. Two different directional filters are proposed and results are compared.

AB  - A PLL frequency synthesizer which (frequency) divider is replaced by a sinusoidal waveform generator has been analyzed. In the generator, n samples of the sinusoidal waveform are generated (created), and (while) the number of discrete points is equal to the dividing module of the divider. By this realization, within every VCO period one sampled value of the sinusoidal function has been generated, it has been sent to the phase detector and together with reference frequency it gives the control voltage. Subsequently, this allows faster reaching of the stable state, which implies high spectral purity of the sinusoidal waveform signal at the synthesizer's output. This approach keeps all advantages of the PLL synthesizers with look-in tables in terms of stability, and in the same time their architecture is much simpler. I
