Develop an FPGA decoder to convert NOAA WAV IQ files into PNG files

Develop and deliver FPGA code in vivado to: Take in attached NOAA wave file (IQ based) and decode it into a weather satellite image. This wave file was a recording of from NOAA satellite's Automatic Picture Transmission. The signal itself is a 256-level amplitude modulated 2400Hz subcarrier, which is then frequency modulated onto the 137 MHz-band RF carrier. Maximum subcarrier modulation is 87% (±5%), and overall RF bandwidth is 34 kHz. Steps to perform inside FPGA: 1. FM demodulator of IQ data to reveal the AM signal 2. AM demodulator using envelope detector (see [login to view URL] as example) 3. Save binary stream to image file (see reference file attached for expected output)
