the establishment as well as the survival of mobile ad-hoc networks relies on the cooperation of nodes for performing network operations such as routing and packet forwarding. in these networks, misbehaving nodes can severely degrade network’s performance by not cooperating in networking operations. in this paper, we study the issue of node misbehavior in packet forwarding. to counter this type...

Bistatic synthetic aperture radar (BiSAR), operates with separate transmitter and receiver that are mounted on different platforms (Cherniakov & Nezlin, 2007), will play a great role in future radar applications (Krieger & Moreira, 2006). BiSAR configuration can bring many benefits in comparison with monostatic systems, such as the exploitation of additional information contained in the bistati...

The scarcity of radio spectrum has become problem in many applications that utilize the higher Radio Frequencies (RF). It is therefore important to manage this resource carefully to avoid the waste. In order to optimize the RF spectrum, in 1997, The United Kingdom launched the world’s first commercial digital terrestrial television service, aimed to switch off the analogue services between 2008...

Broadcast digitalization with its enormous benefits to the broadcasting industry will improve the quality of content of programs delivered by television stations. Africa has a switchover date of June, 2017. For Nigerians to have access to television broadcast once the switch over is completed, they must purchase high definition television sets or the set-up box. The awareness among urban dwelle...

This paper investigates the possibility to improve target detection capability in a DVB-T- based passive radar sensor by jointly exploiting multiple digital television channels broadcast by the same transmitter of opportunity. Based on the remarkable results obtained by such a multi-frequency approach using other signals of opportunity (i.e., FM radio broadcast transmissions), we propose approp...

Video Broadcasting is playing a key role in communication areas. DVB-T has popular Technology for Digital Television Services. In this paper aim was to Implement all function Block in as per specified in the DVB-T (terrestrial based digital video broadcasting) and analyzed using Transmitter and receiver both side using filter. DVB-T 2K mode carriers are transmitted over AWGN Channel. The corrup...

1. Introduction In response to growing internet traffic, the GE-PON system is becoming more widely used as an economic and high-speed fiber to the home (FTTH) service. To enable the broadcasting of ultra-high definition television and other services in the future, it is necessary to expand the capacity of the optical access network, in which 10 Gigabit Ethernet passive optical network (10G-EPON...
