End-to-End Simulation

Waveform generation, signal recovery, and end-to-end satellite communications link modeling

You can use Satellite Communications Toolbox functions to demodulate and decode waveforms. These functions process received signals under an additive white Gaussian noise (AWGN) channel, assuming perfect synchronization and ideal RF conditions.

Examples featured in this section demonstrate how to model end-to-end communications link and analyze link performance. You can use these examples as a reference in verification, performance analysis, and RF front-end testing.
