Description
The objective of the activity is to integrate a number of physical layer advances within an Advanced Air Interface Demonstrator, which will act as a proof of concept. This demonstrator will provide a powerful tool in support of the design of next generation interactive mobile satellite systems.
Targeted Improvements:
- Develop a demonstrator in support of the next generation of mobile interactive satellite systems operating in various frequency bands.
- Increase spectral efficiency and peak data rate of individual user terminals and thereby allowing for a reduction in the cost per capacity unit.
Description:
MSS spectrum in L- and S- bands is very scarce and user expectations of interactive data services are becoming increasingly sophisticated. As a consequence the next generation of mobile interactive satellite networks faces the difficult challenge of increasing the air interface spectral efficiency, as well as meeting the user demand for higher peak data rate. The performance improvement shall be achieved while lowering the overall cost per capacity unit. Similar challenges are also faced by newly introduced broadband mobile interactive networks in higher bands (e.g. Global Xpress operating in Ka-band) which utilize earth station on mobile platforms and the need to share the spectrum with other FSS broadband systems.
Furthermore, the air interface of mobile interactive networks needs to operate with high performance, agility but also with robustness in a variety of operational environments depending on whether the user terminal is land nomadic, land vehicular, maritime, or aeronautical. Existing air interfaces attempt to address all these operational environments and services by dimensioning the link in a rigid fashion making use of high operational protection margins.
Therefore, an advanced air interface demonstrator is foreseen in this activity that will incorporate the latest transmitter/receiver signal processing developments from the physical layer point of view, as well as provide the capability to perform detailed system simulations for a variety of mission scenarios. As a result, the demonstrator will allow for assessing both single user terminal as well as system wide performances.The work logic is as follows:
1) First define the operational scenarios
2) Define the system architectures, type of terminals, and physical layer techniques that will be included in the Advanced Air Interface Demonstrator.
3) Develop the Advanced Air Interface Demonstrator.
4) Test the Advanced Air Interface Demonstrator.
