This paper presents the handover management in mobile satellite communications with multimedia traffic. Multimedia traffic is becoming the next hop in mobile satellite communication, due to its demand. The coverage of the satellite network knows no boundary and with the concept of the broadband satellite network, communication for multimedia and high-data rate multimedia communications can be p...

The CDMA system has been used extensively in satellite communications. This is due to advantages of spread spectrum techniques used in CDMA systems, and their higher capacity in compare to FDMA & TDMA systems [1]. However, since the advantage of CDMA is related to interference level, CDMA systems needs to have perfect power control for minimizing the interference and obtaining required qualitie...

The current researches and industries are looking forward to integrate different technologies to get a global technology that offers all of the intended services in a simple way. In this paper, a new communications system is proposed to integrate the use of GSM over the available satellites infrastructures. The proposed communications system could be used to facilitates and get benefits of both...

Under the rapid development of satellite communication systems and satellite navigation systems, there is an urgent need to combine the two together in order to achieve location-based services, etc. Despite the long relationship history of navigation and communication, the two satellite systems are basically independent of each other. As a result, terminal size tends to be relatively large, and...

Radar systems, based on bistatic radar concept attracted a substantial attention in the recent years. Passive coherent location systems using “transmitters of opportunity” like radio or TV broadcasters, GSM base stations, satellite communication and GNSS signals proved their potential in detection and tracking moving targets over a significant area. In this paper the multistatic location system...

The paper discusses various system aspects of future aeronautical services via satellite. Both, commercial aeronautical broadband satellite communications (AirCom) for passengers and air traffic management (ATM) are considered. An integrated global system design approach is presented, and key R&D issues along this path are discussed. Some focus is laid on geographic satellite coverage and const...

Satellite personal communication services (S-PCS) are one of the recent systems available to global mobile user. The benefits with using satellites are greater coverage, especially in remote areas such as the poles or in the middle of the oceans. However, satellite communication is expensive and for personal use still in its infancy. Today there exist a number of operators delivering more or le...
