The COM-1827SOFT_PCMFM_DEMOD is a non-coherent demodulator for PCM/FM continuous phase modulation with flexible programmable features
  • Programmable modulation index h [0.5 to 0.8]
  • Programmable symbol rate up to fclk/4, where fclk is the processing clock frequency
  • Excellent BER performance using multisymbol detection and 4-state trellis decoding (SOVA). 4-bit soft-decision demodulator output for best FEC decoder performance
  • BER < 10-5 at 9.2dB Eb/No
  • AFC for carrier frequency acquisition of 10% of symbol rate
  • Acquisition threshold < 2dB Eb/No
  • Ancillary functions: BER tester, Matlab code for generating sampled stimulus waveforms
  • Tested on Xilinx 7-series FPGA, but portable to other FPGA types
The entire VHDL source code is deliverable.
