The cloud edge data center will enable reliable and low latency options for the network, interconnection among these data-centers demand a scalable low-complexity scheme. An intensity-modulated directed detected transmission system is an attractive solution, but chromatic dispersion main limitation higher symbol rate systems. To overcome this challenge, we have proposed experimentally demonstra...

organizations are networks of unites and individuals enhancing organizational performance through cooperation and synergy. it is achieved by developing meaningful and purposeful communications of unites and individuals .thus, it is essential to make organizational communications efficient in order to achieve organizational purposes. in this essay, we examined the variables and factors affecting...

Wireless networks are often cited as the most economically feasible solution to the severe dearth of communications infrastructure in developing countries. In the short term, the deployment of wireless networks is indeed the optimal solution to the information infrastructure gap in developing countries. Many developing nations have embarked on this road and a loose formula of employing fixed ce...

civil liability in electronic communications is one the most important issues of information and communications technology (ict) law. civil liability may be arisen from different causes such as copyright and trade mark infringement invasion of privacy and defamation. when discussing civil liability, two different civil liability systems may be considered: direct and indirect civil liability. in...

Global System for Mobile communications (GSM) is a popular mobile communications network. Short Message Service (SMS) is an easily adopted person-to-person communications technology for mobile devices. The GSM architecture allows for the insertion of mass application-generated SMS messages directly into the network infrastructure. This is achieved through a SMS Mobile Switching Centre (SMSC) us...

This paper investigates the Multi-band OFDM (MB-OFDM) based physical (PHY) layer proposal for IEEE 802.15.3a working group on short-range high data-rate Ultra-wide-Band (UWB) communications. An overview of the MB-OFDM PHY layer architecture with its various parameters is presented and the optimal choice of critical parameters is discussed. Next, we derive the theoretical un-coded Bit Error Rate...
