摘要： An apparatus, system, and method of improving the ES/N0 ratio performance of a wireless device. The apparatus, system, and method include measuring an ES/N0 ratio in a communicated return link burst, and, upon failure of the ES/N0 ratio to meet a predetermined threshold, probing for an available switch to a less protested communication mode to improve the ES/N0 ratio. The probing may include transmitting a full power SYNC burst, measuring the ES/N0 ratio correspondent to the full power SYNC burst, and comparing the measured ES/N0 ratio correspondent to the full power SYNC burst to the predetermined threshold.

摘要： 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.
