We investigated the multiwavelet (MW) packet based coherent optical OFDM (CO-OFDM) system. We have shown that MW based CO-OFDM system offers high degree of flexibility and adaptivity in terms of data rate, modulation, and number of subcarriers. MW based CO-OFDM demonstrates better performance compared to conventional OFDM for a transmission distance of about 2000 km.
Data Management System to Improve Security and Availability in Cloud Storage
One of the primary usage of cloud computing is data storage. Cloud provides enormous capacity of storage for cloud users. Secure data storage and retrieval of the relevant information from…
Sequential Markov Chain Monte Carlo for multi-target tracking with correlated RSS measurements
In this paper, we present a Bayesian approach to accurately track multiple objects based on Received Signal Strength (RSS) measurements. This work shows that taking into account the spatial correlations…
Improved Learning Performance of Hardware Self-Organizing Map Using a Novel Neighborhood Function
Many self-organizing maps (SOMs) implemented on hardware restrict their neighborhood function values to negative powers of two. In this paper, we propose a novel hardware friendly neighborhood function that is…
Texture analysis and classification of polarimetric SAR images using histogram measures
In polarized synthetic aperture radar (SAR) image classification, texture produces very significant information about land cover. In order to perform the classification in a much better way, a detailed study…
A measurement study of mobile video streaming by different types of devices
There is an increasing demand for mobile video streaming. In order to improve the QoE of mobile video streaming, it is important to understand the user interest, user behavior, and…
Coupled Attribute Similarity Learning on Categorical Data
Attribute independence has been taken as a major assumption in the limited research that has been conducted on similarity analysis for categorical data, especially unsupervised learning. However, in real-world data…
Enabling elastic services for OSGi-based cloud platforms
This paper presents an architectural design of elastic service frameworks based on OSGi service platforms. Load-balancing and auto-scaling features, among others, are considered as the most essential to enabling the…
How to adapt: SVC-based quality adaptation for hybrid peercasting systems
Live streaming of large-scale events such as the Olympic Games with a huge number of viewers is challenging, as the streaming infrastructure needs to scale fast and big, and often…
Sound source matching LED emotion contents design
In this paper, we proposed LED emotion contents design matched with sound source. LED emotion contents correct inputs signal (sound source) by matching to human emotion. Also, we used liner…
