A New Upper Bound for Free Space Optical Channel Capacity Using a Simple Mathematical in Equality
Journal Title: Journal of Information Systems and Telecommunication - Year 2013, Vol 1, Issue 1
Abstract
In this paper, by using a simple mathematical inequality, we derive a $ new upper bound fkr the capacity of$ free space optical channel in coherent case. Then, by applying general fading distribution, we obtain an upper bound for mutual information in non-coherent case. Finally, we derive the corresponding optimal input distributions for both coherent and non-coherent cases, compare the results with previous works numerically and illustrate that our results subsume some of previous results in special cases.

A New Robust Digital Image Watermarking Algorithm Based on LWT-SVD and Fractal Images
This paper presents a robust copyright protection scheme based on Lifting Wavelet Transform (LWT) and Singular Value Decomposition (SVD). We have used fractal decoding to make a very compact representation of watermark i...
Simultaneous Methods of Image Registration and Super-Resolution Using Analytical Combinational Jacobian Matrix
In this paper we propose two new simultaneous image registration (IR) and super-resolution (SR) methods using a novel approach to calculate the Jacobian matrix. SR is the process of fusing several low resolution (LR) ima...
