Modulation Method and Description
The satellite terminal use O-QPSK modulation under maximum rated condition. The impulse
response of the pulse shaping filter is shown in Figure 4. Transmitted power due to modulation is
shown in Figure 5. The DSP (Digital Signal Processor) programs the frequency synthesizer directly
with the modulating signal.
