Overview

The COM-1852SOFT is a proximity space-link modem for short-range, bi-directional, fixed or mobile radio links, generally used to communicate among probes, landers, rovers, orbiting constellations, and orbiting relays.
The modem is fully compliant with the PROXIMITY-1 CCSDS standard.
More generally, this IP core is a fairly generic PCM/Bi-Phase L/Phase Modulation modem.
The generic VHDL source code is portable to most FPGAs.
