The identity of patients must be protected when patient data are shared. The two most commonly used models to protect identity of patients are L-diversity and K-anonymity. However, existing work mainly considers data sets with a single sensitive attribute, while patient data often contain multiple sensitive attributes (e.g., diagnosis and treatment). This article shows that although the K-anony...

Performance improvement of a power line communication system is presented here considering the noise as a cyclostationary non-white Gaussian random process. Performance of a power line communication system is severely deteriorated by fading and multipath effect. The impulsive noise has been considered time variant, has short duration, random occurrence with a high power spectral density (PSD). ...

This paper proposes broadband packet wireless access employing Variable Spreading Factor-Orthogonal Frequency and Code Division Multiplexing (VSF-OFCDM) with two-dimensional spreading that prioritizes time domain spreading in the forward link and Multi-carrier/DS-CDMA (MC/DSCDMA) in the reverse link for the system beyond IMT-2000. Based on the wireless access scheme, we propose major radio air ...

Last-generation and future wireless communication standards, such as DVB-T2 or DVB-NGH, are including multi-antenna transmission and reception in order to increase bandwidth efficiency and receiver robustness. The main goal is to combine diversity and spatial multiplexing in order to fully exploit the multipleinput multiple output (MIMO) channel capacity. Full-rate full-diversity (FRFD) space-t...

The proliferation of wireless transceivers and the availability of unlicensed band has given a boost to the deployment of wireless networks, with IEEE802.11/WiFi being the major driver in this arena. In this research, we consider a wireless mesh network designed for long distance communication with a typical deployment scenario of a maritime mesh network. This network uses an antenna system mad...

The basic concept of diversity; where two or more inputs at the receiver are used to get uncorrelated signals. aim this paper is an attempt compare some possible combinations diversity reception and MLSE detection techniques. Various combining techniques can be distinguished: Equal Gain Combining (EGC), Maximal Ratio (MRC), Selection Switching (SS).The simulation results shows that MRC give bet...

| Decision feedback equalization (DFE) and antenna diversity combining are two practical techniques for combating multipath fading. In this paper, we investigate the performance of diversity combining together with DFE under various numbers of antenna branches and equalization taps in a wireless communication environment with AWGN and co-channel interference (CCI). Speciically, we present exten...

Diversity reception, is an efficient communication receiver technique for mitigating the detrimental effects of multi-path fading in wireless mobile channels at relatively low cost. Diversity combining is the technique applied to combine the multiple received copies of the same information bearing signal into a single improved signal, in order to increase the overall signal-to-noise ratio (SNR)...
