Direct transmission of biological signals such as electrocardiogram (ECG) and electroencephalogram (EEG) through mobile network provides practically unlimited movement of the patients and unlimited coverage area. However, transmission of such signals

A geometric scattering model that predicts the actual measured probability density functions (pdf's) for the direction-of-arrival (DOA) and time-of-arrival (TOA) is highly desirable. Recently we proposed geometrical-based hyperbolic distributed scatt

In this paper, the problem of fusion of decisions transmitted over Rayleigh fading channels in wireless sensor networks (WSNs) is revisited. The likelihood ratio test (LRT) is considered as the optimal fusion rule when applied at the fusion center. H

In this letter, a combination of 16-state 8-QAM trellis codes with multi-carrier code division multiple access (MC-CDMA) and threshold orthogonality restoring combining (TORC) is introduced over downlink Rayleigh fading channels. In literature, minim

In this paper, we implement Bose-Chaudhuri- Hocquenghen (BCH) coding to study the performance of Power Line Channel (PLC) impaired by impulsive noise and AWGN. Quadrature amplitude modulation (QAM) is employed and orthogonal frequency division multip

Noise in the power line channel can not be described by Additive White Gaussian Noise (AWGN). This channel suffers from impulsive noise and other narrow-band interferences. Impulsive noise, in particular, can degrade the performance of OFDM-based Pow

In this paper, we have derived the circular 16-QAM constellation and apply it in Fourier and wavelet based OFDM systems. In order to derive the circular scheme, we first begin with the derivation of the square scheme as the scale of measurement for t

Impulsive noise is one of the major challenges in power line communications and can cause serious problems in OFDM-based PLC systems. In this paper, we propose a combined Time-Domain/Frequency-domain technique for impulsive noise reduction in OFDM-ba

This paper presents a multiple-input multiple-output (MIMO) space-time geometrical channel model with hyperbolically distributed scatterers for a macrocell mobile environment. The model is based on a one-ring scattering assumption. This MIMO model pr

The study investigated the dependance of absorbed mobile phone radiation in terms of specific absorption rate (SAR) values on head size. A dipole and a generic phone model were used to simulate mobile phone at 900/835 MHz, and standard SAM phantom as
