SYSTEMS AND METHODS FOR INCREASING THE TRANSMISSION SPEED OF A SATELLITE VSAT

摘要

Systems and methods are provided for increasing or decreasing the transmission speed of a VSAT used in a satellite network. A VSAT may include an ASIC and an FPGA in a transmission block of the VSAT. The ASIC includes an ASIC transmit modulator configured to modulate an input information signal, and circuitry for bypassing at least a portion of the ASIC transmit modulator. The FPGA includes circuitry for receiving a signal bypassing at least a portion of the ASIC transmit modulator, and an FPGA transmit modulator configured to modulate the bypassed signal. In implementations, the system uses the ASIC to burst format an input information signal with a payload burst segment; bypasses a transmit modulator of the ASIC after burst formatting the input information signal with the ASIC; and uses an FPGA to insert additional burst segments into the ASIC burst-formatted signal.
