Rate-Splitting Multiple Access for Multigateway Multibeam Satellite Systems With Feeder Link Interference

A Robust MUSIC Based Scheme for Interference Location in Satellite Systems with Multibeam Antennas

In this paper, we investigate methods for interference location in satellite communication system using satellite multi-beam antenna with subspace based schemes. A novel MUSIC based approach is proposed for estimating the direction of arrival of the interfering sources. The proposed method provides super resolution and asymptotic maximum likelihood estimates of the direction of arrivals even at...

Rate-splitting multiple access for discrete memoryless channels

It is shown that the encoding/decoding problem for any asynchronous -user discrete memoryless multiple-access channel can be reduced to corresponding problems for at most 2 1 single-user discrete memoryless channels. This result, which extends a similar result for Gaussian channels, reduces the seemingly hard task of finding good multiple-access codes to the much better understood task of findi...

On Rate-Splitting by a Secondary Link in Multiple Access Primary Network

An achievable rate region is obtained for a primary multiple access network coexisting with a secondary link of one transmitter and a corresponding receiver. The rate region depicts the sum primary rate versus the secondary rate and is established assuming that the secondary link performs rate-splitting. The achievable rate region is the union of two types of achievable rate regions. The first ...

Beam Hopping Techniques in Multibeam Satellite Systems

Forward Link Interference Mitigation in Mobile Interactive Satellite Systems

We present the results of the performance evaluation of polarization-time coding and soft interference cancellation in multi-beam satellite systems a ected by co-channel interference in realistic setups. The standard of Broadband Global Area Network service (BGAN) has been considered as reference for the physical layer and realistic interference and channel models have been adopted. The work ha...
