Abstract: A hybrid carrier frequency offset estimator that uses data-aided and non-data-aided signal processing techniques to produce multiple candidates for the carrier frequency offset within a return channel receiver in a DVB-RCS system using turbo coding and quadrature phase shift keying (QPSK) data modulation. In this system, the invention is employed to estimate signal distortion caused by carrier frequency offset so that this particular source of signal distortion can be removed to improve the ability of the receiver to maintain synchronization in low signal-to-noise conditions. This, in turn, allows the receiver to meet the DVB-RCS performance target, measured in terms of packet loss ratio, in low signal-to-noise ratio conditions and in particular for burst-mode data transmission with a short data packet size.

Abstract: A system and method are described for mitigating interference between distinct communication systems, an interfering one of which comprising a transmitter and transmitting antenna whose transmissions interfere with a susceptible receiver and receiving antenna of the other, wherein at least one of the transmitting antenna and the receiving antenna comprises a directional antenna dynamically reoriented in operation. In general, the system and method are adaptively controlled as a function of a measure of interference compensation effectiveness and variations therein affected by reorientation of the at least one directional antenna.

Abstract: The present invention provides a high-performance and small sized helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by increasing the lateral distances between the antenna elements over a portion of the elements where the windings thereof have high current amplitude. The sweeping envelope of the array is maintained small by recovering the initial distancing over a portion of the elements where the windings thereof have low current amplitude.

Abstract: A joint synchronizer and decoder that implements two decision aided processes, which are referred to as "decision aided candidate selection" and "decision aided synchronization and decoding." Decision aided 'candidate selection may be used to select a carrier frequency offset by selecting among a number of candidates for this parameter based on an indication of decoding success. Decision aided synchronization and decoding may be used for phase tracking based on an indication of decoding success. Although these joint synchronizing and decoding techniques may be implemented together, they may also be implemented independently. The joint synchronizer and decoder may be implemented within a return channel receiver in a DVB-RCS system using turbo coding and quadrature phase shift key (QPSK) data modulation.
