Paired Carrier
Paired Carrier Transmit and receive carriers are overlaid on top

of each other in the same space segment. Echo cancellation

techniques are used in the demodulator to cancel the

transmit carrier and extract the wanted receive carrier

(30 kHz minimum occupied bandwidth; operates to maximum symbol rate of modem)

Supported symbol rate asymmetry Up to 12:1
Eb / No degradation Typically < 0.5dB (0.7 dB for 16 QAM / 16 APSK with 10 dB power

) symmetry
Mobile Operation Uses GPS data to continually recalculate position relative to

satellite, allowing uninterrupted operation in mobile environments

(ships, etc) anywhere in satellite footprint.

providing async baud rates from 0.2% to 5.1% of the terrestrial rate
Advanced Aux Intelsat low-rate async ESC carried In bit 1 of TS32 providing a

synchronous channel at 1/480th of the data rate, allowing up to

one quarter of this rate for over-sampled async data
