COM-1827SOFT GMSK DEMOD, VHDL source/IP core

The COM-1827SOFT_GMSK_DEMOD is a coherent demodulator for the following continuous phase modulations

• MSK, GMSK
• Coherent demodulation (modulation index h = 0.5)
• Programmable symbol rate up to fclk/4
• Programmable bt = 0.25,0.3,0.5,0.7/li>
• Programmable modulation index for FSK/GFSK non-coherent demodulation
• Ancillary functions: BER tester, Matlab code for generating sampled stimulus waveforms
• FFT for large (+/- 12% of the symbol rate) frequency acquisition
• Tested on Xilinx 7-series FPGA, but portable to other FPGA types

The entire VHDL source code is deliverable.
