A high throughput satellite communication system and method of satellite communication that provide loopback capability and increased throughput is disclosed. The satellite communication system and method of satellite communication utilize pre-distortion based on remotely estimated characteristics of a satellite transponder's power amplifier (PA). The pre-distortion is applied to the hub modulator's constellation.

A return channel system for ultra-small aperture terminals has a spreader that receives an input signal and outputs a spread spectrum signal having multiple replicated signals with a lower power than the input signal. A de-spreader includes a de-multiplexer that receives the spread spectrum signal via satellite. The de-multiplexer separates the spread spectrum signal into a first channel having a first signal and a second channel having a second signal. The de-spreader also has an offset compensation circuit having a phase estimator configured to estimate a phase offset between a phase of the first signal and a phase of the second signal. And a phase adjustor that receives the second signal and adjusts the phase of the second signal to align with the phase of the first signal to provide a phase-adjusted second signal. A summer combines the first signal with the phase-adjusted second signal to provide a composite signal.
