COM-1852SOFT CCSDS Proximity-1 Modem, VHDL source/IP core

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 CCSDS "Proximity-1 Space Link Protocol: Physical layer", CCSDS 211.1-B-4, December 2013.
More generally, this IP core is a fairly generic PCM/Bi-Phase L/Phase Modulation modem.

• PCM/Bi-Phase L/phase modulation modem, 60 deg.
• Programmable symbol rate from 1KS/s to 8192KS/s
• Large 160 KHz (two-sided) frequency acquisition and tracking
• Large 1000ppm symbol rate acquisition range
• Tracking threshold Eb/N0 = 0 dB
• Ancillary functions: BER tester, Matlab code for generating sampled stimulus waveforms
• Tested on Xilinx FPGA, but portable to other FPGA types

The entire VHDL source code is deliverable.
