The major objectives of this activity are
The activity also aims at the investigation and demonstration of additional front-end processing to perform apart from
The development of the targeted wideband front end faces as major challenges the
The key features of the aimed wideband flexible front-end allows its application to satellite terminals intended to support a wide range of existing or emerging services, reaching from
The capability of digital beam forming processing at front-end level may even stimulate novel applications/ receiver types such as portable terminals with small multi-feed antennas, characterised by electronically adjustable beams.
In order exploit the widest possible range of potential applications, the following key features for the targeted wideband flexible front-end, being an essential part of a satellite receiver, have been identified:
The wideband channeliser can extract up to 32 independent channels from an instantaneous bandwidth of about 2 GHz (200 – 2200 MHz)
Each of these channels is independently configurable at run-time allowing
The Digital Beamforming has been designed for a typical DTH reception scenario, i.e. a stationary user terminal receiving signals from a GEO satellite. The developed solution is based on a considerably extended MPDR beamforming algorithm. The extensions have been introduced, in order to increase robustness and adaptability against anticipated constant and time varying residual errors.
