    A Data Fusion Methodology for Wireless Sensor Systems

    An efficient DFA (Data Fusion Algorithm) plays an important role in tracking for moving objects over WSS (Wireless Sensor System) deployments in order to track the objects accurately. Accuracy in object tracking is mainly dominated by the prediction for those moving targets by filtering and refining the results from wireless...

    The Joint Impact of FBC and CFO in an Asynchronous MC-CDMA System

    The factor of CFO (Carrier Frequency Offset) definitely degrades the final results of system performance evaluation for an asynchronous MC-CDMA (Multi-Carrier Coded-Division Multiple-Access) system is one of the most frequently discussed issues in every kind of assuming situations. However, the other one important parameter of FBC (Fading Branch Correlation) is...

    The Analysis of System Performance of An MC-CDMA System Over Two-Tier Femtocell Networks

    The paper is analyzing the evaluation of system performance for an MC-CDMA (Multi-Carrier Coded-Division Multiple-Access) system operating over two-tier femtocell environment. The considered scenario is deployed with a macrocell site where is surrounding some femtocells, which are designed to serve a group of subscribers locate in a small coverage area...

    The Design of Large-Scale Surveillance Network Based on GRID Structure

    Brightness obviously affects the pixel value of an image sensor. Image identification from a traditional sensor may generate a bias and surveillant misunderstandings because of weather. The proposed intelligent image sensor integrates an optoelectronic converting circuit and an embedded system and can convert the brightness to an analog voltage. From...

    The Role of Branch-Correlation for an MC-CDMA System Combining with Coherent Diversity Over Frequency Selective Channels

    The diversity schemes include EGC (Equal Gain Combining) and MRC (Maximal Ratio Combining) diversity combining with an MC-CDMA (Multi-Carrier Coded-Division Multiple-Access) system operating in the cases of either correlated or uncorrelated frequency selective fading channels are invested in this paper. The sum of Nakagami-m variates (envelope intensity) is applied for...

    The Performance Analysis of an Multi-Carrier System with Correlated-and Uncorrelated-Nakagami-M Statistics

    In this paper, the system performance of error rate probability closed-form for an multi-carrier spread-spectrum, e.g., Coded-Division Multiple-Access (MC-CDMA) system with linear diversity operating in frequency selective fading channels are evaluated. The sum of correlated-Nakagami-m and uncorrelated-Nakagami-m variates are adopted to derive the closed-form solution with arbitrarily correlated channels which...
