Abstract
We address the problem of interference as related to Satellite Personal Communication Networks (S-PCNs). Basic low Earth orbit (LEO) constellation is considered. The paper uses combined adaptive antenna arrays and adaptive filtering technique. This hybrid linear adaptive technique provides improved performance eliminating interference, particularly uncorrelated signals residing in the antenna sidelobes.

We address the problem of interference as related to Satellite Personal Communication Networks (S-PCNs)
The interference encroachment into the signals received by systems terminals impacts on the quality of desired service (QoS) and grade of service (GoS) as well, and importantly the network congruous scope to deal with the motion of the satellite as well as that of the mobile user [4]
Summary
A Satellite personal communication network (S-PCN) provides universal access to a wide range of services and across transnational boundaries. It faces multitude of challenges those related to user terminals, the space segment, regulatory challenges, [1], as well as technical issues including link diversity, traffic allocation [2], quality of desired service (QoS) and the associated grade of service (GoS) [3], etc. Most mobile stations’ transceivers signals are ideally circularly polarized and isotropic in nature, with a single low gain antenna element These single element units are more susceptible to noise interference because they receive signals from all directions.
